I also had a nerve conduction test where needles were inserted all over my shoulders, arms and hands due to carpal tunnel and other various issues.
As with Luvminis, it wasn't too bad because it was done very fast by a neurologist. The initial stick is the worse but, I'm a big baby when it comes to needles so "any" stick stinks!
I also had injections in my wrists for carpal tunnel (Diagnosed 6 yrs ago but not bad enough for surgery) and honestly, the hand surgeon that did them the 1st time wasn't painful. My pain mgmt. Dr. (same one that does Trigger Points) done them the last 2 times. First time, no pain, 2nd time, he used ultrasound to find "places" to inject & don't know if it's because they've gotten worse but, it was very painful.
For all the "needles" that I've had poked in me by all Dr.'s, I've never had to take a sedative or any pain med other than my normal meds. Did not increase the Fibro pain but the Trigger Points actually decreased it!
