Steroid injection, hip for bursitis. 12 hours later could barely walk. 32 hrs later, swelling at site & pain. infection? what to look for? pa said ice

Infection?: This is often manifested by pain, fever, swelling, redness and there may be chills, generalized malaise. In this situation if you are not substantially improved within another few hours you should be seen by a physician and not a pa. If this is infected it could become very very serious quickly.

Redness...: Cortisone injections can cause localized irritation due to the crystalline structure of the steroid, so not entirely unusual to have worsened pain over the first 24-48hrs. However this should improve, if your pain continues to worsen, develop redness at the area that spreads, then would be concerned. Infections after injections pretty uncommon though. Can try tylenol (acetaminophen) or motrin/naprosyn as well.
