A month ago I took an injection which was to treat an infection, I took this injection daily for five days on both side of my buttocks, then two weeks later I noticed two painful lumps on two side of my buttocks and just few days ago I noticed that the size of my buttocks reduced drastically also my right hip flat, it gets bad, as I also feel strange weakness on my waist and leg, my doctor said I should be patient, but please I need help on what to do, and I'm scared too I don't want this to affect my legs and is there any chance that I can recover the parts of my buttocks that I lost?
