rsd symptoms can come and go and change each day. just because symptoms aren't always there doesn't mean it's not rsd. and rsd can spread to other parts of the body without having all the symptom that you initially had. some drs think that if you don't have all the symptoms all the time that its the rsd is going away or is not spreading. that is not true but unfortunately some drs don't know this because they don't educate themselves enough on this disease. you just have to learn to trust you instincts and listen to your body. you know better then anyone what is normal and what is due to rsd. and finding a good pm dr and neurologist that know rsd helps also. soft hugs to all.
