Brief Answer: Due to tendonitis. Detailed Answer: Hello, Thanks for posting your query. After going through the description provided by you, I feel that you might be suffering with Tendonitis and Tenosynovitis which are both types of tendon injury. They can often occur together. Tendonitis means inflammation of a tendon and tenosynovitis means inflammation of the sheath that surrounds a tendon. The main symptoms are pain, tenderness and sometimes swelling of the affected part of the tendon. You need to give it some rest for a while, use hot fomentation twice a day and local ointment for pain relief. Avoid gripping and lifting objects altogether. Keep it in most comfortable position or use a splint/crepe bandage most of the time (including at night) for best results. Watch for worsening of symptoms like increase in pain, appearance of swelling and tingling numbness in fingers. If you get any of these, visit your physician and get a check up done followed by investigations like X ray or MRI. I hope this answers your query. In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out. Wishing you good health. Regards. Dr. Praveen Tayal.
