Hi, Woke up this morning and i don't know what made me do it - but i started to press under my right armpit. It felt very sore and I felt a pea like lump under there (not on the skin) but deeper under the skin. It's now very sore after me prodding and poking. Any ideas ?? I stated feeling under my left armpit and there's a similar lump there but it's not sore. I'm hoping to go to my GP this week - but trying to get there will be difficult (due to work committments) and I've already started to worry. Thanks all.
