I had this and now it's gone. I did three things differently. I started taking yoga, awesome in so many ways. I started taking magnesium. And lastly but I think most important is I stopped my arm exposure to the sun. I am either wearing really light long sleeves or using sunblock 50+, always. So far so good and it's the end of June.
Hello,
The main cause of BRP is not known but there is evidence to suggest that BRP may arise in the nervous system. BRP may be attributed to a neuropathy, such as chronic cervical radiculopathy.
No cure has been found.The only thing that seems to help most sufferers is the application of ice to the area until the itch is diminished. Other treatments include cooling lotions like those containing camphor or menthol,capsacain or local anesthetic creams,amitriptyline and gabapentin tablets and electrical cutaneous nerve field stimulation.
