I woke with a bump behind my ear I went to the doctor and told me I had an infection and that my lymph nodes were swollen. So the doctor gave me pain killers and antibiotics and two days off work lol 👍. Anyways Ive been taking them I feel like they are helping me but this morning I feel like the bump got bigger. Is this normal? Has anybody gone through this? Should I be worried?
