Hi, I don't know who FM people like either, for the most part. I was dx'd with FM in 1999 after an emotional trauma, job loss at 61. Fight/flight/fright set in my body as it went into a concrete block like feeling. I truly believe so much of the FM issue is firstly thyroid dsyfunction. I finally got on desiccated thyroid support in 2002 and believe had I been on it at time of trauma, my body would have reacted differently. This is my theory after all these years. I had been trying to thyroid supported starting in 1991. 10 yrs of depression led me to believe it was thyroid and the lab numbers told the MD I was normal.....NOT SO. I've also worked on hormones with DHEA for years under my IM's supervision and adrenals and take a multitude of supps including importantly magnesium.

I've never had the twitching you mention, so that has not been my issue.

On your knee replacement, I have had a holy mess from hip replacement in 2010 which made the OA knee worse and the whole body is off from this replacement.

So I chug along at 77 with supps, knee supports, ankle supports and back support. OA started in my body at 18 and here I am hobbling thru this life but prior to my hip job I had done a LOT in my life....no surgery except hysterectomy in the 80's which left me with sciatic nerve damage.

I am dealing with nerve damage from anterior hip replacement which brought me to NT when I was looking for support group re: nerve damage.

I'll stop now with my issues and you may want to say more now. I've taken none of the drugs for the FM issues which as I've read long time back, FM is close to rheumatism but with a modern day name and new drugs.

I hope you get some insights here. Welcome.
