Lump on lower back of neck
I have this lump, located at the lower part of my neck. It's pretty large (about the size of my fist). I have been in several car accidents a few years back and threw out my back completely. My lower back is still in pain (always on the right side) and I'm wondering if the lump has something to do with that? The lump doesn't hurt but it's bugging me and I can't wear my hair up when I wear a strapless dress. Any ideas? I go for a massage on a regular basis and I do get adjustments at the chiropractor but neither on of them has mentioned it to me before. Should I be worried? Thank you!
