So I awoke in the middle of the night with my finger left ring finger burning and itching. Now everytime i bend it it feels tight around the joints and if I bend it, touch it or scratch it the burning itching feeling starts again. Can anyone tell me what i might have I think it might be spreading to the rest of my hand but im not sure. So far its just my left ring finger. Im pregnant by the way if that has anything to do with it.

Thank you.
