Ok My wife the nurse gave me the gluteal shot 2 cc's in the left butt cheek. It swoll up the next day, even swelling my lower back on that side. It doesn't cause me to much pain but it aches, feels like a large not. The muscle is almost rock hard. What should I do. I gotta soften it up. Also anyone know why it would react that way? I am thinking about having my friend just wail on it hard as he can. I may pass out but I figure that should loosen it up. Whats the best way to loosen it up? I have been bathing in epsom salt twice a day since.
