De Quervain’s Tenosynovitis, also known as thumb tendinitis, is a painful condition that affects the tendons on the thumb side of the wrist. It occurs when these tendons become irritated or inflamed, making it difficult to grip, lift, or twist objects.

The pain often develops gradually and can be made worse by repetitive movements such as texting, lifting a baby, or using tools. In some cases, swelling and stiffness may also appear at the base of the thumb.
At Rebound Physio in Chester, we provide expert treatment for De Quervain’s Tenosynovitis. Our goal is to relieve pain, reduce inflammation, and restore smooth, comfortable thumb and wrist movement through evidence-based physiotherapy and personalised care.
The thumb and wrist are supported by several tendons that allow smooth movement and grip strength. In De Quervain’s Tenosynovitis, two key tendons are affected the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These tendons pass through a narrow tunnel, known as a sheath, on the thumb side of the wrist.

When these tendons are used repeatedly, friction can build up inside the sheath, leading to irritation, swelling, and inflammation. This makes it difficult for the tendons to glide smoothly, resulting in pain and stiffness near the base of the thumb.
The condition is often seen in people who perform repetitive wrist or thumb movements, such as lifting, gripping, or scrolling on phones. It can also occur after a sudden strain or injury. Without proper treatment, inflammation may worsen and restrict normal hand function. Early diagnosis and targeted physiotherapy can help restore mobility and prevent long-term tendon damage.
The symptoms of De Quervain’s Tenosynovitis usually start gradually and worsen with continued use of the wrist and thumb. Pain is typically felt on the thumb side of the wrist, especially when gripping, twisting, or lifting.
Common symptoms include:
Symptoms often become more noticeable during activities that involve repetitive thumb movement or lifting. Without treatment, the pain may persist or limit hand function, making it difficult to perform everyday tasks comfortably.
De Quervain’s Tenosynovitis develops when the tendons on the thumb side of the wrist become irritated from overuse or repetitive strain. The constant friction inside the tendon sheath leads to inflammation, swelling, and pain with movement.
Common causes include:
Risk factors include:
Identifying these causes helps guide treatment and prevent recurrence by addressing both tendon irritation and underlying movement habits.
At Rebound Physio in Chester, we offer expert diagnosis and treatment for De Quervain’s Tenosynovitis to relieve pain, restore movement, and prevent recurrence. We begin with a detailed consultation to assess wrist and thumb function, identify contributing factors, and create a tailored treatment plan.

What Our Clients Are Saying
EXCELLENT Based on 132 reviews Posted on Rose FloydTrustindex verifies that the original source of the review is Google. Mark was very informative at the consultation, and didn’t rush me into the injections. I went back 7/10 days later and it’s now been a fortnight since they went in. Previously I had pain daily and couldn’t walk very far. I am now enjoying being pain freePosted on Hannah-May ElmasryTrustindex verifies that the original source of the review is Google. Really knowledgeable and friendly physio, fully assess and explains things thoroughly would highly recommendPosted on andy muirTrustindex verifies that the original source of the review is Google. Mark is a wonderful knowledgeable practitioner, he explains things perfectly. I had hip steroid and hyaluronic injections and are feeling the benefits already. I would highly recommend Mark to anyone.Posted on Rebecca BensonTrustindex verifies that the original source of the review is Google. Worth his weight in gold. This guy has been a godsend to me. After experiencing extreme levels of pain for three weeks with whiplash after a car accident.. I’d tried another physio as well as attending my GP several times for medication and nothing had touched me. I was becoming depressed with the level of pain I was experiencing… Mark did an extremely thorough consultation, talked me through options and got to work. After my first session I felt some relief, though the benefits continued throughout the day; That evening was the first evening I didn’t have vice crushing headaches from moving my neck downwards and that night was the first night I hadn’t woken up in the middle of the night needing to take pain medication. The following day he did more work on the front of my neck and I practically floated out of the place. I really can’t recommend him enough. For the first time in three weeks I see some light at the end of the tunnel. I’d never experienced pain like it before, but he’s really made such a difference in such a short space of time. Professional, experienced and a lovely person. Thank you so much.Posted on Robert SerkisTrustindex verifies that the original source of the review is Google. Highly recommend seeing Mark Boundy I had very bad hip problem which had lasted a year Mark administered a cortisone and lubricant injection 10 months ago the pain eased very quickly and it's improved to where I don't have a problemPosted on darren rossTrustindex verifies that the original source of the review is Google. Booked in to see Mark regarding a hip/glute issue. Following an initial consultation I booked a dry needle appointment (which he managed to get in the same day for me) provided immediate relief to the issue. Was prescribed some exercises and stretching to help moving forward. Great service, reasonably priced and provided clear answers to all my questions. Good to know I have a reliable option for any future problemsPosted on Wayne PriceTrustindex verifies that the original source of the review is Google. Shoulder pain for a long time got unbearable. And literally 1 visit and within 3 days pain freePosted on Debbie TaskerTrustindex verifies that the original source of the review is Google. Finding Mark has been life changing, I have had years of back problems since the birth of my second child, After over doing it at the gym, I was in terrible pain and discomfort, a feeling I deal with often, We found Mark, so friendly, helpful, and extremely knowledgeable, he was able to help me with dry needling, which made a huge difference to my ability to move better, along with physio which was intense but so amazing, moving forward to where I am today! After feeling so broken for so long, I see the light at the end of the tunnel all thanks to Mark 🙏🏻 Forever grateful. Thank you 🙏🏻Posted on Emma WheatTrustindex verifies that the original source of the review is Google. Mark was recommended to my hubby who was suffering with a very bad knee. Lots of pain when walking/bending and very swollen. I dropped him off to have his knee assessed, he was impressed with the ultrasound scan Mark did (got alot more information about the state of his knee after 15 minutes with Mark than after an MRI with NHS!). Steroid & thick oil were given as an option as the knee was a bit of a mess, osteoarthritis and cartilage torn. Mark offered no guarantee but it was deemed worth a try. It was the right decision. 3 weeks in and there is no pain - used to be constant pain. Less discomfort - used to ache. No swelling. The result is he can now walk & kneel down better than he has in about 20 years.Posted on LesleyTrustindex verifies that the original source of the review is Google. I can’t rate Mark highly enough. I previously visited him a few years ago for Achilles heel pain and swelling which he swiftly assessed was related to issues in my hip and after a few sessions he resolved my issue. When I had pain in the ball of my foot recently, I visited him again after the NHS were unhelpful. Mark immediately knew that I was suffering with Mortons neuroma for which he administered a steroid injection guided by ultrasound. It’s very clear that Mark is very skilled and knowledgeable in his field, he also makes you feel very at ease and explains the whole treatment process carefully. Even though Mortons neuroma tends not to go away completely I am now almost pain free following the treatment. I would highly recommend Mark to others.

Mark Boundy

After completing a Biology BSc, my journey in physiotherapy began in 2004 at King’s College, London. I spent eight years in the NHS, where I saw how long waiting lists and short appointments hindered effective rehabilitation. This led me to pursue an MSc in Manual Therapy in 2015, becoming a member of the MACP.
I moved into private practice at Oxford Sports Physio & Pilates, where I helped rehabilitate high-level athletes, including GB rowers and Oxford University sports teams. Today, I’m an expert generalist with a passion for treating a variety of musculoskeletal issues.
While I don’t specialize in one area, I have a keen interest in using MRI machine for diagnostics and injection therapy, which allows me to offer precise, effective treatments. Combined with medication prescription, I provide a comprehensive range of musculoskeletal care.
