Lupron and heart palpitations

After my 2nd monthly shot of Lupron I experienced heart palpitations and high blood pressure. I felt as though my heart were going to burst while I was laying in bed trying to fall asleep. I saw a cardiologist who prescribed a BP med. Now I am on 1 medication to combat the side effects of another. I am due for my 3rd shot. I am buying time until my hysterectomy. I am worried that this 3rd shot will be stronger and worse than the first 2. I do not have any other worrisome side effects.

I read up on Lupron and was very hesitant in taking the shot, However, my doctor convinced me that it would be helpful with my Endo which is a stage 4. My doctor said well any medicine is like a restaurant if the side effects are bad then everyone knows just like if you get bad service.
Well I got my first shot about a month ago and I think I should have listened to myself, I traded one pain for a ton of others.
I have severe depression at times and the bone pain is almost more than I can bare. I live on Advil to keep the pain under control. I can barely get out of bed in the morning b/c I hurt so bad and I can barely walk. I am losing hair and it is thinning out horribly. I too have put on weight with regular exercise and watching my diet.
I get heart palpitations to where my heart feels like it is going to jump out of my chest and this is the first month. I am afraid of what the next month will bring. I am only 35 and didn't want to get a hysterectomy.

I am so thankful that I found this site....I thought I was going crazy when I started experiencing vision changes. My mother told me that vision changes with age...I knew it wasn't because I turned 35....I received a 3 month shot Sept. 2004..once it hit my system it literally took me off of my feet. I was in the bed for 7 straight days with muscle spasms, no appetite, insomnia, headaches, anxiety....elevated blood pressure and heart palpitations...The blessing in this is that I switched doctors and now will not have a mymomectomy at this time, which was scheduled for Nov. 2004. Prayerfully the tumors won't grow and I can carry a baby.
My question is....will everything go back to normal once the medicine wears off? I am waiting for a cycle and praying that I will be normal again...I sometimes cry and get so mad at myself for not holding off my decision to take the shot...I trusted my doctor over researching first.
If you trying to shrink tumors....I don't think the shot makes a great deal of a difference...and I have friends who had surgery without lupron and they were fine.
