I am experiencing strange and sudden foot pain. I am 42 years old and just returned from a vacation where I was
walking alot but had no injuries to speak of. Suddenly, after resting one afternoon, I stood up and could barely stand or walk. The ball of my left foot was so so painful and slightly swollen. It went away after arnica gel, ice and standing. Now every time I lay down for awhile it hurts again really bad. On the ball of my foot and on the top. I felt the metatarsal bones and they seem slightly swollen or knotted on my left foot, but not my right. What coudl be causing this? Thanks.
