Firstly what you describe with your hands and feet, sounds very much like Raynauds.
Now You say your mum has Scleroderma, Have you been tested for this?
Raynauds, just doesnt come with Scleroderma, Raynauds can come alongside many other Auto-immune Diseases.
However because off the way you have described Raynauds, i would go and tell the doctor what happens, and ask to be tested for further Auto-immune diseases.
I find Auto-immune diseases, can run in families.
There is medication for Raynauds if it is bad, but you doctor can advice on this.
Good Luck, if you need anymore help just give me a nudge.
I am a Raynauds sufferer, so i know how painful, and discomforting this is.
