Yes, I have a knot or something on the outside of my right leg, I noticed it about 3 weeks ago. It was red, hot and sore about the size of a quarter. I thought it might be an ingrown hair. I put Caladryl lotion on it for 2-3 days and it seemed to get better, a few days later it did the same thing, so I treated it the same way, then it seemed a little better. Yesterday it started again but seems a little bigger and more tender. There is no sign of an ingrown hair that I can see, or any opening or anything. Do I need to see my family doctor for this?
