Hi, may I answer your health queries right now ? Please type your query here..I have experienced dull aches in my check area, on my left side, and have had difficulty breathing while walking and going up inclines more so now since my doctor removed what she said looked like an angry-looking spot from my back under my left shoulder area. I have squamou cell carcinoma. Another spot of squamou cell was rd from my chest right under my neck. My throat feels thicker (3/4s of my thyroid was removed a few years ago. Could this be related to the skin cancer? No mentioned these other symptoms to my doctor with deep soreness and harder time with breathing.
