Whilst having a lovely back massage today the lady who was doing it stopped and asked me if where she was pressing hurt because there was a red elongated ump there. (It's on the left hand side just at the bottom of my rub cage) It didn't hurt until she pointed it out and pressed on it and it's been a bit sore since. Should I see how it is in a couple of weeks or book an appointment with my gp to have it checked out on Monday? I don't want to waste the docs time.
