I've had just about every symptom you mentioned....the tingling, twitching the pain, etc. and they are all symptoms of Lyme disease. And I wonder if your husband might have it too. I'm pretty sure my husband has it. Just remember that it can mimic other disease or be a major factor.
I know, doctors, UGH. But I did need one to order the Bowen test for me so I went to one to get that done.
One thing that's really helped me (and _BOB if you've ever read his story), is I bought the book "From Fatigued to Fantastic" and everywhere it said "chronic fatigue/fibromyalgia", I just replaced it with "Lyme". Since they are one and the same disease anyway, there is a lot of good info about natural rememdies in there.
The biggest lesson for me is that Lyme is extreeeeeemely tenacious. I was a cleansing and herbal queen and it just drove me into the ground anyway because I didn't understand that it is DESIGNED to almost completely evade our immune systems. Our bodies simply don't recognize that it's there.
So, now armed with that knowledge, I am following the F to F protocol and being patient and waiting at least 3 months before I expect to see any progress.
