I have been experiencing swelling, pain and burning in my arms, hands, wrists, fingers, feet and ankle for over a month now. Since Wednesday the pain has gotten worse and is now constant and accompanied with a back of the head headache. It is so bad that i am having trouble walking because the bottom of my foot is swollen and hard and one of my ankles gives up when I put pressure on it. I had a baby in March and since giving birth I only urinate once or twice a day but I always keep myself hydrated. I drink over 8 bottles of water daily. I m not sure if that has anything to do with the pain. The pain is severe as is the burning sensation.
