I am a 42-year old guy. About a month or so back, I noticed a pain in my left hand and my thumb on my right hand. The pain is not in any joint but rather BETWEEN the metacarpal bones (I think that's what they're called) of my left hand that run from the wrist to the fingers. And same with the thumb: the pain is between the metacarpal bones and not in the joints. It is much more noticable when opening a jar or turning the steering wheel of my car, but other that that there is no pain. There is no visible swelling or redness in the area that would otherwise indicate inflamation, and at night there is also no pain whatsoever.
The underside of my left foot also aches on occasion, especially when I take the first couple of steps in the morning, but the pain (which feels like 'walking on beach sand') seems to vanish completely after about 30 seconds of walking.
I must admit though that I have been indulging in copious amounts of alcoholic beverages of late as I am going through an extremely stressful divorce, but I am unaware if drinking is related in any way to the pain in my hands and left foot...
What could this be? Any suggestions?
