Hi Doctor I Was Mowing My Lawn About A Week

Hi Doctor I was mowing my lawn about a week ago and got stung on my right gluteous max cheek. I did'nt see what stung me but the following day it was welted and itchy. I did not pay much attention to it but three days later I started having really bad pain in that hip joint. I went to see my doctor and he put me on pennicillin. He also told me to take motrin for the pain. Motrin helped sometime. still having pain
