So for a few days on and off my left index finger has been tingly. It's just the tip of my finger and it is on and off. I work as a server and use my hands a lot. I've been wondering if it's just a burn. It feels like there is a string around the first joint of my finger. Not to tight but just annoying. I can still move it and feel things so it's not completely numb just a little tingly. Thanks for any help you can give
