Hi, I started taking oxy elite pro yesterday and it gave me a lot of energy. I only took one pill. I did a lot of house cleaning. I have pain in my upper right shoulder. It is hard to lift my arm. I'm not sure if this is related to the oxy elite pro or a result of all the house cleaning I did. I think I remember felling a slight numbness in my arm after taking the pill before I started cleaning. I didn't get the severe pain until about 7 hrs later. I took Ibuprophen (sp) last night and it feels better, but the pain is still there. I am overweight and I take prozac for anxiety. I hardle ever drink anything w/ caffene in it. Could my arm pain be a side effect oxy elite pro?
