For more than a month or so, i noticed that my left thumb has turned nearly blue nearer to the tip of the thumb. It only hurts if im using it to hold something heavy. Other than that it doesn't really hurt.
Just recently i feel when compared to the other thumb, its cold.
My doctor apparently can't tell me what it is, but intends do help me do a blood test.
He mentioned that from my previous blood test, that diabetes is not possible.
All the causes i searched from blueness and coldness in thumb except of thumb injury sounds like im screwed. Is that anyone out there that has the same problem or is able to tell me what is happening?
thanks in advance
