Waxing

Lily

I have been waxing my own underarms for a few years now and I've never had any problems. However, I did it recently and not I'm feeling 3 painful lumps in the area that have persisted for the better part of a week. I cant visually see any in grown hairs or anything like that, but it is extremely painful to move my arm.

Any clues to what this is and or if I should see someone?
