a natural defense mechanism - to the sudden increase in exogenous hormone levels. Its the body's way of trying to "flush" out the foreign entity it perceives is there (just as it does w/ a flu virus). There has also been some connection between high BA content and immune response. think the combination of sudden increased hormone levels and a foreign substance being injected into the muscle can cause these symptoms. Some people are sensitive, some arent. Certain people don’t experience it at all and some might just get mild chills (low grade fever) or a runny nose for a few days and not even take much note of it.
I am a 54 year old male. I developed bumps on the back of my neck and forearms, with herald patch on my shoulder blade. My doctor friend diagnosed pityriasis rosea via multimedia text. I noticed on Friday, diagnosed Friday night, and started tanning bed and antihistamine with colloidal oatmeal and two applications of Head and Shoulders. Today is Monday, and spots are drying and not as itchy . I put on shampoo like lotion. Coating skin, allowing to almost dry, and then shower 2 times a day. It seems to be working for me. Good luck. I think I was fortunate to have a doctor friend who diagnosed as soon as I noticed the bumps. I am a diabetic, and keep a close eye out for things that are out of the ordinary. I have a tube of lidocaine hydrochloride 2 percent that handles what the antihistamine and oatmeal doesn't. My best advice is don't delay, make friends with a physician. Biggest puzzle is how and why I got this. This needs to be resolved. Being told there is no cure and no known cause, and no real treatment because it's self-limiting is nonsense. Because I know of no studies on this, I can't say if it is the shampoo, or the colloidal oatmeal, or the tanning beds, (2 trips in 4 days, will wait a couple of days before doing that again) or the tea tree oil or the lidocaine or the cortisone 10. I tried them all, and after 4 days I have marked improvement, less itching, healing welts, and a high degree of optimism. Hope this helps some body.
