My question is similar to the person below. I get random goosebumps on my lower left arm on the front only and a little on the back of the same arm around the elbow. The come fast like a tingling first. They only last raised less than a minute, but I can still sort of feel them under my skin for a while after. They come in the same pattern every time. A non-symmetrical patchy pattern. It's been happening for at least 10 years, but happens less than less than every month, but more than once over a day when it does. I'm not on any medications other than ventolin for asthma and Tylenol or advil for arthritis. 46 years old, smoker. Between 5-10 concussions over life, 2 where blackout resulted. Twice fractured lower back and compressed neck diving in shallow pool.
