My entire right index finger became swollen for no reason, approx 1.5 times larger than normal size. I could not bend it and it was kind of red.
On occassion I get a swollen area on my hand or finger that then turns purple and blue as it heals over a couple days, but it is because I hit something or squeezed something tight.
I also have always had cold hands and feet.
Does anyone know what this might be or what might be causing it?
