My husband recently developed a big hard lump on the front of his left leg between his knee and foot. It is hard to the touch Other than bad headaches he is in pretty good health. This past year he went to WW and lost 115 lbs.Do you have any idea what it could be?

My boyfriend has the same problem. He said that about 2months ago he notice a red rash on his left leg, and this past Sunday he told me that he had a lump the size of a marble on his spin area (between the knee and ankle). My boyfriend is a smoker he has been smoking for the past 10years, so you already know he's freaked out and so am I. He said that it would her when he lays down, and it would also hurt when he walks. When I check his leg today it appear as though the lump has gone, but I'm still going to suggest he sees the doctor, and I suggest you do the same because lumps growing under the skin are never good idea.
