<s>[INST] for the last two days I have feelings of little spark like small star sensation that repeatedly but sparadically i feel set off on the surface of my skin on my arms, legs, face, chest. it may be in small clusters of 2-3 or single and may present like popping popcorn then stop for 5 min and start again. If I could make a visual it would look like the ends of lit fire crackers then go out last 3-5 sec.
