I have a hard lump or mound sort of thing on my left thigh muscle (outside). It feels deep and attached to the muscle (the lump) It also has caused a red scaly dry circular rash on the outside on my skin sort of 1.5 inch diameter. Im going for tests. can anyone relax my brain ? And assure me this isn't the signs of skin cancer/ sarcoma (or something) maybe as my doctor seemed worried . It's come around in the last 6 months or so and my ex misses worried me more cos I've been complaining about leg aches and joint pain etc . Doing my own head in anyone had any experiences? Or similar?
