Kenalog and blood clot

I was having Kenalog injections into my knee. On the ninth injection within a years time,with a few Aristospan injections in between, my knee to my foot blew up. Tripled in size, and the skin was bright red with purple marks all over the skin from my upper shin to the ankle bone. I had a big depression in the shin too, which I can not figure out because the injection was into my knee.
I went to my GP who sent me to the ER to rule out a blood clot-ultrasound.
NO blood clot. I was given no medication, nothing, and it was very painful.
Actually, I saw three doctors and not one of them seemed to care. One doctor said, "Steroids are Powerful Drugs" I do not know if this reaction was do to an infection, some side effect, I have no idea. The swelling eventually went down within six months=long time. I still get purple round marks on the skin at the shin, and sometimes my ankle swells. The skin gets red and white marks mixed into the already rash looking skin.
I asked many times what the cause was to this all, and it was like no doctor would say anything negative about the doctor that gave me the injection.
I also discovered that Kenalog is used off label for Epidural Steroid Injections and can cause Meningitis, Arachnoiditis, bowel and bladder dysfunction and more adverse events, because neurotoxins are added to the steroid to make the compound that is injected into the epidural space. Asking other people if their doctor ever told them the drug name they were getting injected by their doctor before this procedure and each and all said "NO."
This is also true for the drugs Depomedrol and Celestone Soluspan. All three drugs are used off label for epidural injections. Neurotoxins do not belong in the spine! If one gets a dura puncture-FOR GET IT!

I had an injection of Kenalog on Tuesday, Feb.21, 2006, between L5 and S1, right and left side. The following day I had flushing in my face and neck. I had also hit the back of my hand on that day. When I looked at my hand it had a small round bump on it. I didn't think too much of it until I looked down about 15 minutes later. The small bump turned into a VERY large bump, taking up about 1/4 of the top of my hand. I immediately put ice on it and it did not get any larger but it didn't get smaller either.

I called the Dr.'s office and was told that I was having an allergic reaction to the Kenalog as far as the flushing went. He prescribed Vistaril for the flushing and told me to put hot compresses on my hand the next day.

The hot compresses was supposed to break up the blood clot but so far it hasn't. Yesterday I noticed that the skin below the clot is very discolored (kind of red and kind of purple.

He said that the combination of Kenalog with the Plavix and full dose of aspirin I take daily made my blood vessels very weak and one broke.

I also experienced chest pains the night of the injections. As yet, I am still not feeling very well.

I had no clue there would be so many adverse side effects and wonder if I should continue with treatment. He told me they would not use Kenalog again but they would have me take Benadryl before the next injections and take Vistaril afterwards. If I do this, how will I know if I am allergic to the next drug?
