Thank you, Dr. Smith, i just looked at the dermatones image, and im thinking that my arachnoid cyst in my thoracic region is the culprit.

I will ask my neuro about this tomorrow.

I DID ask my Neurologist and pain mgmt specialist about this. He too was stumped. Said it sounds like it has to be coming from the arachnoid cyst on my thoracic spinal cord area, but he's never heard of this either. I told him the itching migrated from 100% of the time on my left nipple, to now about 60% of the time on my nipple, and the other 40% of the time on my upper arm, underside......

He said he'd ask around, see if he can find any info on it. I'm still itching, it's maddening! Scratch, scratch, scritch, scratch!

I know you said your mammograms have been clear, but that connection between breast & upper arm sounds familiar... You might run this by your gyno or whoever... (?)

Doc

I certainly will. I'm due for a new mammo in 2 months. I'd better check sooner. I've seen friends die from cancer in less than 2 months!
