I've had this about 6 years or so.

This was first suspected by me as BRP after doing lots of research on gabapentin which both my daughter and I were taking, confirmed by a neurologist and a pain specialist. The neurologist ordered an MRI which confirmed his diagnosis of impingement and stenosis at C5-C6 of the cervical spine. I also had nerve conduction studies and an electromyography which was abnormal.
Hope this is helpful to you.

Yes! And no explanation to date. It's just a good feel to know it's real and that I'm not the only one! Thank you for explaining your situation/pain/feelings and everything inbetween!

I will be 59 in Jan. Mine started probably about 8 yrs ago if I remember correctly. It's random and can go for a long stretch he without it like many months and then BAM! I've tried Aloe directly from the plant, calamine lotion, aloe in a bottle, medicated powder.. with only a slight bit of diff but I would say that the Dermatologist gave me a steroid based prescription that is a clear ointment and I think it helped a little too. He hadn't prescribed it for this but for a little Ezema on the back of my forearms but also this itch thing hasn't been diagnosed.

Mine Will calm down for a couple of days after I apply a water bottle full of ice cubes all night on my forarm. I fall asleep with the bag of ice againt the itch. I must numb it into submission. I've tries every ointment without any luck

I will scratch like mad! But it has to just go away on its own. It gets red from scratching so much and like you, no rash, NOTHING there when it strikes!

Oh, it's real, alright!!!! Very very real!! Although there is no rash, I often leave marks on my skin where I scratch and dig until I bleed. I have scars from scratching.

I've done THE EXACT SAME THING! During our last hurricane here in FL, Irma, when we had no ice, I thought I would literally go out of my mind.

I leave red marks as well. It's very intense and very crazy.

Are you in the keys?
