I am experiencing pain in the thumb of my left hand, precisely in the middle part of thumb (joint of Metacarpal pollicis and Phalanx proximalis). It started yesterday, slowly in the beginning and, within few hours, became very sharp and severe. It appeared at intervals and lasted during the night (couldn't sleep). Now, in the morning, the pain is moderate. The pain appears with feeling of „pulsing“ and the thumb is warm and a little bit swollen.
Note: there is no pain in the lower part (base) of my thumb.
I am male, 59.
