Hello, Doctor, I have been carrying around my 15-month-old daughter since she was born. As a stay-at-home dad, I lift her all day, all week long. Over the last 2-3 weeks, I have been experiencing a sharp pain in my left hand, on top, between the thumb and index finger. This pain appears when I am lifting our daughter in and out of her crib, into/out of her car seat, and similar lifting situations. I bought a compression bandage at CVS. After weeks of the pain slowly getting worse, as well as migrating back towards the wrist, it seems to have stabilized. Am I on the right track? Is this a tendon issue?
