Okay, so for quite a while now I've been having these really odd symptoms happening to me. The three most common places this happens is my heels, my knees, and my right pinky toe and the whole side of my right foot. From time to time at random I will feel a very tingly sensation and I will notice the area is beat red and hot to the touch. It also seems swollen. It mostly happens on my right knee/foot but today it happened on the left heel and started having a very strong pain to it. I've been tested for blood clots, limes disease, and even gout but they have all come back negitive. I really want to know what is going on. Please help?
