I have been receiving Kenalog injections in my deltoid for allergies from my m.d. each fall for the past 4 years with no incident. Six weeks ago, Nov. 19 2007 I went in for the same symptoms and received the same injection of Kenalog in my deltoid once again. This time it seemed to be unusually painful but I thought it was just poor placement of the needle and did not think much of it. Now after six weeks I have developed a depression/ indentation in my shoulder at the site of injection that has grown to the size of a golf ball and is lumpy and soft even when I flex the muscle. It also has discoloration with splotches on the skin. It still aches and is getting more painful. After visiting my doc. today he seems concerned and claims he has no idea what it is and is sending me to the labs for more testing. In the mean time this is very strange and costly. After finding this web page it makes me wonder how could he have no clue as to this side effect? I am a otherwise healthy 30 year old male, except now I have a very weird looking shoulder.
