Kenalog and infectious disease

As a fairly healthy 34 year old male, I went to my doctor for help getting over poison ivy mid-July 2008. I received the Kenalog 40 injection without being advised on any potential side effects. Within 36 hours I started having severe anxiety attacks with spikes in my blood pressure and vision problems (spotty, increased sensitivity to light). These attacks continued for 4-8 weeks during which time I underwent an MRI (head), stress test, and blood work to make sure nothing else was causing my symptoms.....conclusion: everything normal. My doctor prescribed me Xanax to help with the out of control anxiety. Started feeling more normal 60-90 days later. I started trying to run on my treadmill to get back in shape at the 90 day mark, and once again....symptoms returned. It's been a couple of weeks and I'm getting closer to being back to "normal", but I have no idea how long it will be before the Kenalog has completely metabolized out of my system, and I can get on with life. This has been a horrible experience and I would caution anyone from receiving this drug!
