Hi a few years ago I somehow managed to sleep on my inhaler and it left a large lump which was there for about 5 days was very sore. Since then I the same spot I've had a pea size lump can't really tell if it's movable...sometimes u can feel it more than other times. I went to the doctor when I first noticed and he didn't seem concerned...but I suffer with health anxiety and its really.triggered me off again is it worth going to the doctor about it again? It's located on the back of neck but towards the left side
