question about Decadron

I dont know whats happening, but after being on Armour for 14 days -9 days out of those my temp. is below the 97.7 of which is low. My b/b is up and down and heart rate. I feel ok when I get up for an hour and then start getting hyper again, and have taken medicine an hour before rising. 60mg and I split the dose-am and pm. By pm I am still hyper and take dose and start to calm down the rest of the night. I was feeling better after doctor decreased from 90mg to 60mg for few days, now this again. Plus my eyes are worst, both swelling and hurt bad,worst than before~! Reported symptoms and said to come in if I wanted for an injection or Decadron- a steriod for the inflammation. Never had one before, only Predisone 40mg for 8 days orally and had to stop as thought I was having reaction, shortness of breath, heart rate up. What do you think? I am afraid of it, but eyes hurt so bad will almost try anything! anyone else had the injection? Its used for many things but suppresses the imune system, so I am a bit concerned. I am told to cut armour in half now and see how I feel. Dont think it will make a difference, as I suspect I am still hypo going by temps. Any comments would be apprecitate.
