I'm 18 weeks pregnant and have 2 small (pea sized) lumps under my right armpit. I knew they were there because they are quite sore. Bit concerned about what they could be as my mum gets quite a lot of cysts, but if that was the problem would they be so sore? Out of the country at the moment so not going to be able to see doc for a couple of weeks. Anyone had something similar and turned out to be fine?
