I have severe PLMD. During my last sleep study, at which I only slept 4.5hrs, I had 512 recorded limb movements with 97 resulting in an arousal, giving me a PLM Index score of 108, with anything over 25 considered severe.
Thankfully, I only rarely feel a little of the urge to move my legs when awake, usually just before going to sleep. I don't have any of the other RLS problems that many on here have like pain, daytime jumpiness, etc. The only real problem is that I start jumping and jerking soon after falling asleep and most nights it ebbs and flows all night long, resulting in daytime fatigue and brain fog. It also at times is quite disturbing to my wife's sleep.
I was hopeful that brain iron was my problem and had the tests done that are recommended in the Mayo Clinic document, but my results were all well in the normal range, with ferritin actually high at 336ng/ml.
My doctor said I am not a candidate for iron therapy based on those numbers and has offered to start me on a low dose of Gabapentin, but said he usually only suggests that for people suffering with the typical RLS symptoms.
My question is will Gabapentin do anything for PLMD without RLS. I'm reluctant to start it and possibly keep increasing the dose if it mainly is for the pain and discomfort relief of RLS which I don't, at least so far experience.
