Wow! I thought I was going crazy. After reading all of these blogs, I am experiencing the same exact symptoms. I woke up one morning after excercising the day before and had a rash that started at my feet and ankles and was extremely itchy. The rash moved to my elbows and forearms, and I felt weak and numb in my hands. The next day, I still had the rash and felt numbness in my hands and my feet and hands were both red and swollen. The bottoms of my feet and backs of my ankles were extremely itchy to the point that I have given myself scratches. I went to the doctor who was unable to give a diagnosis-other than the Rheumatoid arthritis, but could not figure out why I would have it. I was given blood tests and was also given a steroid shot to take down the selling, but a day or two later and I am experiencing the same symptoms and can barely type due to the swelling in my hands. The only things that I can think of that I have done in the past month are that I drank a half of a glass of Kendall Jackson cabernet savignon and awoke the next day with the worst hangover I have ever had, I was pulling weeds one day, and the other thing is that the last thing I did was to excercise with weights where I was somewhat over exerted. Otherwise, I am relatively healthy, excercise pretty regularly and do have some allergies but not to explain these sudden symptoms that came back after treatment. I have not received any response about the results of my blood test, but based on these blogs that I have read, I am thinking this is a strange anomaly.
Also, I have experienced the same issue with the numbness and tingling in my hands. I have noticed this problem in the last several years and have not really done anything about it. The appearance of this condition I would not have made a connection except that the swelling in my hands came the next day after the rash and the numbnes in both my hands. It is extremely itchy and since the shot wore off, I can barely feel my hands and my feet hurt when I walk and are both swollen and red.
I was devastated when I started reading that this might be some type of autoimmune disorder. Lupus did not make sense as the rash usually appears somewhere on the face. The doctor thought of rheumatoid athritis, but since I did not have a family history or some type of virus, he did not make the connection as to how I would get it. I did read somewhere that sometimes RA can come on rather suddenly as a result of an injury or physical exertion. I also read somewhere about allergic reactions coming on after exposure to extreme cold or heat, which in my case happened after being overexerted during excercise.
