Hi Ana21, good to hear from you & with some helpful suggestions

, thank you.
Night sweats are v longstanding, nearly 2 decades, every night & continue to wreck my sleep, with frustrating effects on fatigue & stamina.
Lower back pain
has thankfully improved somewhat in recent weeks, but neck's not likely to with spondylosis & various other joints & muscles/tendons/ligaments seem increasingly fragile.
No B12 deficiency whenever tested, whether on or off supplements & try to keep levels up as per Endocrinologist advice.
I take D3 tabs, but at only 200 iu as I find they consistently worsen slow gut transit at 400 iu or higher, though research (fairly recent from memory), found good D levels were important for normalising gut transit. Probably didn't include thyroidectomised patients, or those who don't adequately convert thyroxine, so also have to take T3.
Calcium always fine when tested & phosphorus never flagged as abnormal.
Awaiting recent blood test results, with Endocrinology, Physiotherapy & Orthopaedics appts coming up, all within a few weeks. If that lot doesn't throw any light I'll think again. May need to go back to Rheumatology.
Thanks for posting. I hope you're OK?
