Hi there, 

Going out on my mind with worry, my left underarm feels more muscular than my right, but as I have a problem with my right shoulder caused from bursitus and impingment i assumed my left just had more muscle because of not using the right as much, I noticed this a few months ago, I have now noticed a smallish like soft lump near the underarm muscle which doesn't move and I am completely freaked out,  I was at the hospital the other day for something else and mentioned it, the dr couldn't find any other lumps in my breasts and said they look symmetrical but to pop to my gp, I have an appointment tomorrow.  I cant function and constantly crying I cant help thinking the worst,  the more I feel it the bigger it feels. Please someone reassure me.

Thank you
