My mom says she has constant pain on her right thumb finger at the place where the finger connects to the hand. Can't say if it is the bones or the nerves but she can't fold the thumb finger, says the nerves are pulling it in and she's having this issue for almost a week now. Sometimes she could feel the pain all the way up to the shoulder and the pain is increasing. Is this a serious problem? If so, Who should I consult? P.S. She doesn't have diabetes
