I had a run in with Gout one time, have no idea what caused it (might have been the shrimp, asparagrus and beer I had for dinner). When I got out of the bed in the morning the joint where the toe connects to the foot hurt so bad that I almost could not walk.
The next day it was just as bad and a person at my work that has had Gout many times recommended eating a bunch of black cherries and drinking a ton of water.
That day I had about 7L of water, did not eat any meat at all and ate an entire bag of black cherries. The next day my toe still hurt but not that bad and I could walk on it again, each day I pounded water and if I had meat I went with chicken. All in all it took about a week to get back to normal.
Still drinking as much water as I can and watching the red meat and seafood as I do not want to have that happen again
I agree with others, go see a doctor, if it is gout there is stuff they can give you to help get rid of it.
