I had a microscopic lumbar discectomy on my L5-S1 on Feb 5 and felt no pain after the surgery. Made the mistake of coughing hard on Feb 10 that brought sharp pain down my leg which turned into a dull ache. Doctor says I most likely just irritated the nerve and didn't re-herniate the disc. Last night the pain was sharper and I got my period today. Has anyone else experienced an increase of sciatica pain during their period after back surgery?
