My prayers & best wishes to your wife & you. I’m going through similar experience with my wife. She needs a cane for stability (age mid 40’s) and aches so bad she can’t sleep. Plus constant migraines. Doctors here can’t finda thing wrong (mri’s, spinals, all kinds of test) they think possibly an autoimmune disorder but not sure. I personally think doctors suck and it’s all about money.
I wonder if that "low something" is Vitamin D?
