Official medical explanation. It's an MS thing. A damaged sensory nerve let out a "Yelp". If it keeps happening, yes, let your neuro know. My neuro wants to know of all new and persistent sensations or problems that affect your functioning. Jumping ans wincing in pain, even though the wince is long after the sensation is gone does affect you. This sensation alone would probably not qualify as an exacerbation, but that call is up to a neurologist.
Let us know what develops. Quix
If all of these symptoms are happening on the same side and are new, maybe you should give your neuro a call and let him/her know what's going on. Especially if they last more than 24-48 hours.
I wish you well! Pat :)
Bumping this up hoping someone else may be able to tell me if this warrants any additional concern...Quix? You there?
Wish I knew more, but I can certainly offer this: I would visit your neuro asap and determine if this is an exacerbation. Quix would know more.
