I have a fairly new area - my left upper arm (perhaps the musculotaneous nerve). My fingers, hand and thumb on this arm are tingly as well. I have had other 'areas' on my body appear, disappear and then sometimes reappear over a period of time.

My symptoms of PN and AN started about 17 years ago. I developed gastroparesis last summer and then the tingling and numbness in my right arm, face, mouth and head. I was more recently diagosed with SFN by skin test and am currently being evaluated for AN. The pain in my upper arm has bothered me continually for about eight months or so.

It is hard to understand why this happens. So random.

Hope your discomfort gets better, Mere
