TweetIm not a dr, but sounds like you didnt inject deep enough into the glute. You have to use a 1-1/2g pin and go almost all the way in with it, or you will get a lump. Try taking ibuprofen/Motrin 2-3 tabs, 2-3 times a day and warm compress ( you can use a warm wash cloth. It will help blood circulation to that area. Sounds like the worst is over. I know guys that have taken antibiotic at the first onset of this happening, just to ward off any possible infection. It should go down. Is there redness or changes of color i would perhaps seek a drs advice.
