While stretching my toes one day, I suddenly felt a painful burning sensation at the top of my big toe where it joins to my foot. Now when I sit with my legs outstretched I can’t move my big toe without it hurting at the joint. I get a painful burning sensation that lasts for 30 seconds. With my legs bent I can move my big toe without much pain, but there is still throbbing. Any ideas on what I did? I am a male, 47 yrs old. Thanks.
