had melanoma in my left calf in 2004. Dermatologist dug it out and said it hadn't spread. Now on my right leg below the knee I thought I bumped something & that was why the area hurt. Six months later still hurts to touch it but I just found a lump. Quite painful. I would like to add that I called 911 last week because I thought I was having a heart attack. The hospital found numerous nodules on both lungs & there was a shaded area behind my esophagus. I was sent home & told to call my doctors. Stress test did not go well. Could be blood clots or thicken artery (I take Atenolol 25mg & Taztia120mg daily). Seeing a pulmanary doctor next week. What do you think. I think melanoma that has traveled to my lungs.
