unexplained urge to stretch my hamstrings

[Darcy2000]

Sleeping is very illusive for me . Lately as soon as I hit the hay this urge comes over me to stretch my hamstrings .It is primarily in one leg .I do not think it is Restless leg syndrome . This will go on for 3-4 hours til I finally take a pill or some benadryl. I am not anxious , things in my life are very stable. As soon as my leg sees the bed it starts acting up🙄

I am on Pregabalin which is for nerve irritation a separate issue.I take one of those and a melatonin 5 mg before bed …It not help my crazy insomnia

Waiting to see my GP.

ANY THOUGHTS?
