One of the things that makes me humble without fail. yooooo I do not wish it upon anyone.
I also have the same problem. I now use this cream
instead of normal body lotion, I bath with the new sunlight bath soap and use Rupanase pills.
Even these pills work wonders. One pill twice a week and I dont experience this rush anymore.
Try these pills I guarantee you they'll work. One of the things that caused this rush for was when I ate chilli or spicy food, but since I've started using these pills I can eat anything.
Seeing that we are talking about skin. These remedies for psoriasis.
Staying away from anything with perfume or colourants, soap, body creams, body washes. Use Pure products available at dischem and know your triggers.
Change in diet, eliminate meat and oils. Stick to veggies and lots of fruits.
Coconut oil also works wonders in these field.
For others, it's food (red meat), tomatoes,gluteand they have to stick to an alkaline diet and stress is one of the biggest triggers.
Scrub with activated charcoal sitting on the sun in the morning for that vitamin D and also use baby skincare products.
I once had the very same problem and it is the most painful allergy that I have ever had for two full rain reasons. Afer having tried almost everything and failed, an Indian doctor suggested Tetmosol soap! It worked!
Tetmosol soap is a GRADE I medicated soap. It is mainly used for treatment and prevention from scabies and related skin problems like itching, skin irritation, inflammation, rashes, redness on skin. It also works against head and body lice. It can be used for entire body! Try it
