I think I may of damaged my nerve in my armpit or done something to the muscles? I was digging it and prodding it for weeks looking for lumps still haven't felt one I haven't been prodding all the time for the past week but still now and again my armpit feels really odd and my arm feels weird sometimes my armpit looks a bit swollen compared to the other one :( but now my mind is telling me I have lymph node cancer this HA is really annoying me :( xx
