While bartending I felt a pain a little above my armpit where my bra strap was when I went to feel it, I found a hard little lump which is a little painful. When I finally came home from work, I checked the lump and realized I had a prominent bruise over it. It's been about 9 days and the hard little lump is still there and the bruise is slowly fading but also still there. I also woke up to a small bruise with no lump on my chin which doesnt hurt and I have no idea how it got there. Help me!
