I am in a lot pain on my right side. Mainly when my little one latches on. It radiates to my back and into my right arm, and i am very nauseous. I am not pregnant i have taken a test. I have also checked for a lump but can't really find one. I have had a very low fever and been completely exhausted. I just feel miserable and in a lot of pain. Does anyone know what this could be?
