Found another small lump.

Hi,  0ne year ago I got a small hard lymp node under my armpit,  I went to My Gp and they referred me to breast clinic to tell me it was nothing to worry about, I started to get funny rashes on torso and groin area and have swollen lymph nodes in neck and groin as well, I developed another lump the side of breast when drinking over Xmas was swollen and painful,  I don't know if i should see doctor again?
