Sunflower, There is really nothing to it. I am also sensitive to all drugs, but this is just like a novacaine. I never even felt the needle go in. It was on a tender spot on my back too. You will be fine. Just tell yourself that as you go for your appointment. For anxiety I take Standard Process Min-Tran. It is a mineral tranquilizer. You can only get this from a health care provider. I go to a Natural doc. I must have 15 different Standard Process items I take. They are whole food supplements and they won't hurt you. Standard Process makes another product that I am told is stronger but I will have to find out the name for you on my next visit, which should be one day this week.
