YA. I'm starting to feel very nervous. The doctors are starting to say things like not sure what else they can do, and permanent......thankfully its hasn't progressed beyond slight mottling, and the pain, and coolness. The pain spikes up and down, I have good days and bad. Sometimes I have a few days that are nearly pain free! At those times I start thinking maybe it's going away! And then it comes back with a vengeance.....I'm sure you all know how that is. The pain free days are few and far between, I am still waiting to see the Neurologist and am trying to get into a "pain" clinic. I really need something stronger than Tramadol when I have my normal daily spikes. and definitely when I have my bad days!! I DID get more sleep last night thank goodness, my arm had calmed down from the night before, but I could feel it starting to gear back up. so I slapped a Lidocaine patch on before it got too bad......ahhhh sweet sleep! lol I hope you feel better soon!
