I finished a 2 month treatment of Cipro for Lyme Disease back in February. Up until recently I have felt a lot better. The majority of lyme symptoms are gone and the others I hoped would get better with time. Lately I have these burning sensations on my arms and legs especially when I lay down at night. I also have had days when I wake up it would feel like my sugar was low and I would feel like crap until I ate something. My docs ran some blood tests and my vitamin b12 levels is low and my thyroid T4 level is low. I'm guessing this was either caused by the Lyme or the 2 month antibiotic treatment.
I also had low vitamin D levels and if I stop taking them daily my levels drop again. For some reason my body is telling me the Lyme is gone. I don't know what to do about the low vitamins and thyroid which has me worried. Anyone else have these issues? What should I do to correct my levels or will I ever be back to normal again?

To fix the Vitamin D and Vitamin B12, go to a local health food store and find supplements of these. The best form of Vitamin D to get is Cholecalciferol, or Vitamin D3. And if I were you, I'd try to take at least 1000IU/day, and you may need more initially (the Endocrinologist told us that the body uses between 2-4000IU/day, and sometimes more).

Vitamin B12 can be taken sublingually. It is inexpensive and safe to take in large doses (your body won't absorb what it doesn't need). I personally prefer the methyl-B12, but cyano-B12 (cyanocobolamin) is fine for most people. Look for a supplement that has at least 1000mcg. per sublingual tablet.

Foods high in Vitamin D include oily fish (salmon, tuna, etc.) and sea vegetation (such as the dark stuff that sushi is wrapped in sometimes). Foods high in Vitamin B12 include meats and liver, but food-sourced Vitamin B12 requires adequate stomach acid levels, a healthy stomach lining, and a healthy terminal ileum (the last part of the small intestine) in order for it to be absorbed.

I'm surprised your doctor didn't offer you prescription versions of these nutrients, because being low in both can cause low energy, and low B12 can lead to permanent nerve damage if left untreated.

And for the thyroid, a simple iodine supplement may be helpful, but you might want to consider prescription thyroid support in might be good to talk with an Endocrinologist about your thyroid test results.

I hope this helps - take care,

B12 deficiency can cause a lot of issues. People who live closer to the equator get more vitamin D from the sun -- naturally -- have fewer aches and pains in general.

Glad you feel that you beat this! That is great news.
