Excruciating pain in 4th toe
Every few months/years I get this sudden onset of just intense pain shooting through my 4th toe on my left foot. It is perfectly fine when resting or with no weight on it, and I've even tried many times to poke and press and push it while not standing on it to see where it hurts, but nothing. However, when I put weight on it when standing or walking, it is so painful I literally fall over.
The very first time it ever happened was when I was about 20 (7 years ago) and I was on a train. I got up to get off the train, walked to the door as normal, opened it and stepped out onto the platform, and when I stepped down onto this foot, I had to sit down on the ground in front of everyone (who looked at me very strangely) as my toe was so painful.
I then had to try and walk around with my weight completely on the big toe side of my foot for about 5 days, (which was very painful for my foot, as it felt constantly twisted and strained around the arch of the foot) and after this time, if I forgot and put weight on the toe/foot, it would send a strange tingling almost painful numbness but no real pain. A few days later, it was fine and back to normal again.
I have no idea what this is. It's happened numerous times, all very sudden and then vanishing again within a week. I cannot put ANY weight on the toe at ALL when it's happening though. Several times if I was sitting or lying on my bed and then got up to do something, I'd completely forget the toe and go to walk and then actually collapse straight to the ground, gasping in pain and clutching the now burning and tingling toe.
Any help!? (it's not broken. I've had a broken toe before and it's not as bad as this)
