Looking for advice. This year i've had all the symptoms of chronic fatigue syndrome -- specifically, low B12, low thyroid, exhaustion, constant sore throat, headache. I've been treated for B12 and thyroid (thyroxine), self-inject B12, had negative IF test (for what that's worth) and still feel lousy. Loading doses of B12 from GP had me feeling fantastic for 2 months, but then relapsed, and even injecting every other day makes no difference. Same with thyroxine -- felt great for 2 months, now back to square one. Have no idea how often to SI, whether it's helping, whether I'm not absorbing..... B12 and thyroid now registering normal (B12 very high) in blood tests. What next???
