I have had brachioradial pruritus in my arms for 20 years. Severe itching that occurs typically at night. The only thing that has worked for me is a product I got from a dermatologist a couple years ago called TriCalm. I understand they are about to formally launch the product soon. They have a website up where I think you can get a sample. The stuff was a heaven send for me.
Hello,
From your symptoms brachioradial pruritis needs to be ruled out. It is an intense itching sensation of the arm usually between the shoulder and elbow of either or both arms. The itch can be so intense that sufferers will scratch their own skin to a bleeding condition.
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. I sincerely advise you to consult a dermatologist and get it ruled out.
I hope it helps. Take care and regards.
