Yes I have them too. I asked a PA about them once and was basically told the same thing.
What is your diagnosis? Are the knots still there and do an they really press on the surrounding nerves (which would make the feathery sensations)? I can't get any answers from anyone on this site. Should I damand to see a neurologist? It's hard to get a referral unless I show other signs/symptoms of a disorder.
My main diagnosis is DDD and all the little ugly things that go along with it.The feathery sensations sound to me like a nerve irratation.
