I started an exercise program about two months ago that uses resistance bands for arm and bicep strengthening I seem to have injured my thumb. I thought it would go away but has been six weeks now and I still have pain when doing certain things like lifting and pouring a coffee pain or lifting a heavy book. The pain runs up the top of the thumb into the hand above the joint. What would be the cause and do I need to do anything about it?
Hello, One possibility may be that you have developed a tendinitis.  There is a form of tendinitis in the thumb area called de Quarries Tenosynovitis. Without examining you it is difficult to tell, but certainly this could be a possibility. In the first instance, I would ice the area for about 5-10 min, 6 times a day. Taking over-the-counter medications such as ibuprofen would certainly help.  Sometimes in the case of tendinitis we would prescribe a wrist and thumb brace.  This is sometimes called a thumbs pica splint.  Occasionally for persistent tenosynovitis I will insert a small cortisone injection into the tendon sheath, which can give significant relief. I would suggest seeing your primary care physician or an orthopedic specialist, for a further consultation. I hope this helps.  Please message me back if you have any further questions.
