Thanks for the mention of the Betamaethasone cream prescribed by your dermatologist. I have been using Triamcinolone Acetonide cream, 0.1% off and on for years and it has been only slightly and inconsistently helpful. It looks like the Beta stuff is a stronger steroid cream and I will try to get a doc to prescribe some for me to experiment with. Being a stronger steroid, have you noticed any of the side effects mentioned in the info sheet that comes with it?
Also, I noticed your comment about taking Benadryl (diphenhydramine HCL) every night for sleep. If you are not taking the generic version, it is cheaper and the same thing, but you probably already know that. At Costco, I found something that helps me sleep far better than that substance. It is called Kirkland Sleep Aid and is also an antihistamine. The chemical name of the antihistamine is Doxylamine Succinate @ 25 mg. Also, it is very reasonably priced, but I don't recall the amount. There is a slight indentation on one side of the tablets to guide you in cutting them into two pieces, which is what I do, and 1/2 tablet lasts me all night long for about 8 hours. You might feel groggy in the morning when you wake up, but at least you slept!
Finally, I never had Grover's wander to parts of my body other than the front and back of my upper torso until just recently. Now it has been popping up on my arms, legs, hands and feet. It's a good thing I am retired and live alone in my own home because putting clothes on over all those sores can drive me CRAZY! HAHAHA
