Kenalog and crawling out of my skin

I am a 35 year old male in perfect health. last week i received two Kenalog injections in my trap muscles to to treat muscle spasms{trigger points) from a pinched nerve in my back. When I went home later that day as I layed down I begin having severe heart palpitations. I went to my doctor and my blood pressure was very high 169/94 with a heart rate of 127. For the last week I have been experiencing anxiety attacks, insomnia, hot flashes, sweating, nervousness jittery, very emotional. I had my heart checked out and had bloodwork drawn all normal. I was put on lopressor 50 mg 2times per day and xanax to help me sleep at night. I am crawling out of my skin! I can feel my heart beating all hours of the day and night! It is driving me crazy!! I regret getting the injection!!! The doctor told me it could take 2 months before the steroid leaves my body. I hope I will not have any lasting affects of the drug! I am very nervous these symptoms will not go away! I also am experiencing headaches and burning in my stomach. I am also always hungry and yet I am losing weight.Im thinking about seeing an endocrinologist. Im scared!!
