@dennismm reading your post….can you recall what you might of done prior to the pain coming about? Did you have any kind of infusion? Did you fall or get hit by something? Between having Ankolosing spondylitis, which gave me a lot of leg cramps and burning throughout my legs. Then I had Bladder cancer and while receiving treatment it was suggested that I have a Urolift implant due to enlarged prostate. The burning was so bad they had to remove what they could of the Urolift; leaving the nylon clips because they are on the back side of the prostate ( only way to retrieve them would be to remove a fair amount of my prostate and I felt intimacy would be zero and felt it still to be a part of my life, so I declined the removal of the prostate). This caused a constant burning sensation anytime I would void and would subside as time went by until I voided again. Then it was recommended I received a Reclast infusion due to potential complications from osteoporosis. I received the infusion, flu like symptoms started, which was expected. Then all of a sudden….left foot and both shoulders pain, nausea, fatigue, blurred vision, muscle aches and pains then like electrical shock in my lower back into my groin area and thighs. It has been 27 months and I’ve been to all kinds of specialists and not one can explain my symptoms and yet they want me to receive another infusion! No Way! Best of luck to you!
