A couple of months ago I started having hip pain mostly at night, lower back pain and more stiffness. It didn't occur to me that it could be the B1 until I read someone else on HU mention that they had hip pain.
I've been taking B1 since January 2018. Started with 4000 mg but pretty quickly adjusted to 1000. When I realized it could be the B1, I suspended it and a week later the hip and back pain and the stiffness was about 75% gone.
Yesterday I took 500mg to see what would happen, and last night hip pain woke me at 4am. So it's pretty clear that it's the B1.
I'm wondering if I might fare better with injections. Any thoughts?
