What is carpal tunnel syndrome?
Carpal tunnel syndrome is a relatively common condition that develops when the median nerve – a major nerve that provides sensation and muscle control to the hand – becomes squeezed or compressed as it travels through a narrow passageway in the wrist (the carpal tunnel). Because this passageway is very rigid, it has minimal capacity to stretch or otherwise increase in size to accommodate swelling in the surrounding tissues. In particular, if the synovial membrane that lines the wrist joint becomes inflamed due to overuse or arthritis, it can take up significant space in the carpal tunnel and pressure the median nerve.
What does carpal tunnel syndrome feel like?
The symptoms of carpal tunnel syndrome may include:
- Pain, numbness, tingling and burning sensations in the hand, especially in the thumb and index, middle and ring fingers
- Intermittent shock-like sensations that radiate from the wrist to the thumb and index, middle and ring fingers
- Muscle weakness in the hand that makes it difficult to perform fine movements, such as fastening buttons
- A propensity to drop objects due to a loss of proprioception (awareness of the positioning of the hand)
- Pain or tingling sensations that travel upward from the forearm to the shoulder
In many cases, the symptoms of carpal tunnel syndrome develop slowly without a specific injury. Many people first notice discomfort after holding an object, such as a phone or book, with a bent wrist for a long period of time. Over time, the pressure on the median nerve may increase, causing the symptoms to occur more frequently or persist for longer periods of time.
How is carpal tunnel syndrome treated?
When carpal tunnel syndrome is diagnosed and treated early, its symptoms can often be addressed effectively without surgery. Some options include:
- Bracing – A brace can be worn during certain activities to keep the wrist in a straight or neutral position and reduce pressure on the median nerve.
- Nonsteroidal anti-inflammatory drugs (NSAIDs) – Over-the-counter medications such as ibuprofen and naproxen can help relieve pain and inflammation.
- Lifestyle modifications – Activities that involve holding the hand and wrist in the same position for an extended period of time – particularly if the wrist is flexed or extended – often aggravate symptoms.
- Corticosteroid injections – Injecting a powerful anti-inflammatory medication directly into the carpal tunnel can provide lasting (but temporary) relief.
- Physical therapy – Physician-recommended nerve-gliding exercising can help the median nerve pass more freely through the carpal tunnel.
If nonsurgical treatment does provide effective relief within several weeks, a physician may recommend a surgical procedure to relieve pressure on the median nerve.

Always treated promptly and kindly at AOSM. Thanks to Dr Mack and his team.
Dr. Cubbage & Staff replaced a disc that had been destroyed between my 4th and 5th vertebra. This is my 4th month since the surgery in January of 2018. I was very impressed with their dedication
So I was going to get on here and brag about what a great surgeon Dr. Cubbage is. But Cubbage is only 3/4 of the picture. He’ll fix you, but Karen is the one that will care for you and heal you!
Dr. Patel has been a great Doctor for me. When I was referred to after discussion we decided to do injections in my back.
Dr. Mohr and his staff are very friendly people. They treated my father very well and made him feel comfortable in his uncomfortable situation.
I had been in so much pain with my back for years. It got so bad that I knew I had to do something. I went to Dr Mohr for help. I was so afraid to have spine surgery as I had heard so many horror stories.
I have been fighting chronic knee pain for ten years following a knee replacement, a bone infection, and subsequent knee revision surgery. After a number of failed solutions to pain relief, Dr. Patel introduced me to RF
Dr. Patel is one of the best Doctors I have ever had. She is pretty good at her job. She makes it plain and simple. She is also very thoughtful. I was very glad to have met her.
