I know this is an old thread, but I like to make a point of chiming in on something as drastic as HELL ITCH. I like many of you who suffer from it, wish I were dead when it's flarring across my back! I have been this way most all of my life and as someone clearly stated above it's because our bodies release so many histamines during the healing process.
So, the other day I got duped into a 4 hour tube ride down a non shaded river at high noon (Don't ask how or why, I was just lied too) and they left the lotion back in the locker so no reapplying it, needless to say sunburn ensued. Anyways, 48 hours rolled around and like clockwork *BAM* ""HELL ITCH"". Worst part too is that I had work in 4 hours.
I managed to survive eight hours of stocking shelves overnight shift with HELL ITCH, and I will explain to you how. I researched about the oil and how it works and so on, so I picked up some Peppermint Oil, but your not supposed to apply it to the skin without a carrier oil. So, when you dilute it the heroic effects aren't as strong, however it was key to my survival. Pay attention to this next part because it'll save your life with HELL ITCH!
HELL ITCH is the body over releasing histamines<<<<< that's a key point right there! To survive work I had to ingest 50mg of antihistamines every four hours. I used Benadryl Allergy and I assure you it is God's gift to man when they suffer this wrethed cur. Now I had to move alot during my shift, bending, lifting, and running, the benadryl alone wouldn't have done the trick because of having to wear a collared shirt. So, this is where the peppermint oil came in, I cut the peppermint oil with almond oil, and applied it thickly to my back, then I put a 100% cottons white shirt on over the oil and under my rough collared shirt. So, while the antihistamines fought of the release of the histamines, the oil kept the clothes from irritating my back even further!
So, I am a survivor of strenuos work while suffering HELL ITCH! My advice to you, is pick up and dilute peppermint oil with a carrier oil and pickup Benadryl Allergy and keep it with you at all times, because the moment the antihistamines wear off you will know it immediately and wish you never left them at home! I promise you this works, and has been tested under extreme working conditions. I hope it helps someone else!!
