Banalg and arm muscles

I use Banalg for a messed up shoulder and muscle so I can sleep at night. I didn't expect any side effects but I got one anyways and a good one to boot. All my life I have suffered severe skin irritations and unsightly red spots on my upper arms, entire back and buttocks. These irritations are much like oversized pimples with lots of puss and very reactive to touch. I started to use Banalg for my upper arms so I could fall asleep at night from the intense pain in the arm muscles but when I looked the next day the unsightly skin irritations where fading so I continue to use this stuff and every night more and more of these irritations are disappearing. I don't know how this is happening but for the first time since I was a little boy, my backside and arms are almost smooth and defect free again. I'll be shirtless this summer.
