I have limited systemic sclerosis and Raynauds and have had ''unscratchable'' itchy skin on and off for years. It is only relatively recently that my skin has begun to bleed underneath when I've had a bout of scratching (I know I shouldn't but how do you NOT scratch?!?!?): I end up with terrible bruises on my legs. Also, lately on my left hand and foot I've had bad itching followed by little blisters (no bleeding) which then burst and am having trouble getting them healed. Not sure if it's just another symptom or a side effect of meds ... any ideas, similarity please?
