Kenalog and allergy season

I went to see my PCP in March 25th 2008 because my allergy. My pcp told me she'll give one injection since it's allergy season and it would make me fell better. She didn't tell me what kind of injection it was and I trust her.

The next day I was having panic attacks while I was outside on the street.
I couldn't breath because my heart was beating so fast, and I felt "pacey" all day. I just went home hoping the symptoms go away but it only got worse. I couldn't even walk because I was out of balance, my vision got blur and I had massive headache. I assume it was happening because the injection so I called my PCP, but she told me she didn't do anything different. My PCP had a day off so I went to the ER that afternoon. I had cat scan done in case I had stroke but my cat scan was clear. The ER dr think it's side effect from the shot.
I called my pcp 2 days later after my visitation to the ER but she never returned my call. Somehow, I couldn't trust my pcp I didn't go back to her.
I was hoping the injection fades away and try to manage my body. I start notice I had anxiety and couldn't sleep at night. I had pretty regular period but I had very irregular period following month and that drove me crazy because I had 2 full periods within a month and I had blood spots. I barely had period following month. I notice that I gain so much weight. I always watch what I eat so I never get out of control with my weight but I couldn't fit into my jeans I used wear. I also notice that I get back pain the side I had shot if I seat for long hours which I never had before. Now my legs are swelling ,numb and have tingling sensation. I was really concern so I call my pcp today to find out what kind of steroid she injected me. The medical assistant told me that doctor can't not give the name and he was giving me ridiculous excuses to not to give me the name of the injection . I was so upset and didn't make sense to me. I asked for the dr. and asked my pcp the name of the shot. It was "Kenalog". I googled the name and I found this site. I am really scare and I am upset at my pcp that she never mention what the injection was and never discuss the side effects with me. If I knew about the side effects back then I would never let her give me the shot.
I never signed anything with my pcp. My pcp promise to call me back today. I even left her a message again to call me but haven't heard from her yet.
I believe FDA is responsible for this steroid but doctors are holding great responsible also!

How long dose it takes to get back to normal? I would greatly appreciate for any information!
Dose anyone knows powerful lawyer?

I have received kenalog injections (only one) per year during allergy season for severe allergic rhinitis. I was recently out of town and was miserable and tha local ER would not give me the injection. The reason was beacause it can cause avascular necrosis especially involving the head of the femur. Which means it can slow down the blood supply to
the top of the femur and cause the bone to die. I had never heard of this before and I will probably still take this injection as planned when I get back to town.
