Diagnosed with Raynaud's 2 months ago. Warmer weather makes no difference. Fingers of left hand still numbing. Now left arm weak and agonising. Can't even dry off after shower without severe pain in upper arm. Left radial pulse weak and red spots appearing across left fingers and palm. See GP next week. Do I ask whether I have scleroderma.....? Or wilI sound like idiot who consulted Internet and got too much info.....?
