A few days back I suddenly noticed a striking red spottted rash in my lower leg under the knee , on the side. And when I was wondering and found I saw a small lump deep inside on top of the red rash. too There was very little pain when touched on it, and also very little pain on rash. I went to a General Physician. He is not s specialist and told could be a beinign fatty tissue. It looked like a bruise - now kind of healing, turning to bluish purple with very little tenderness when touched. No other pain when walking and all. But I still see this lump inside, very small. Looks like the lump had breaked inside and bruised under it. 3 weeks back I had a fever and doctor told it could be bacterial infection. Also for around 6 months I have kind of pain in buttocks but it could be because I sit long in chair as I am a software conusltant. Do i have to worry about this small lump inside. Wat should I do.? Please help. Thanks.
