I'm not a doctor, so I don't know how to interpret your results. Have you been tested for mycoplasma? Sometimes that is responsible for asthma and can cause other problems throughout the body. Did you have your Lyme test through IgeneX lab? Did they also test for co-infections? IgeneX has far more comprehensive results than the mainstream labs. Also, have you been checked for heavy metals, mold toxicity, pfiesteria, and ciguatera? These also produce neurotoxins that can create fibromyalgia symptoms.
Looking at your list of conditions, this is what I speculate is going on: your gut is full of toxins due to improper digestion (it's likely that candida is overgrown since you've got osteoperosis--sounds like you're not absorbing minerals), and gut toxins are absorbed through the lymph nodes, signaling changes in the brain stem that allow the release of inflammatory cytokines. The cytokines awaken brain glia, which in turn is causing your seizues, and possibly also the fibro symptoms. If all of this is this far out of balance, your endocrine system starts to get unhappy. TPO is a good test for Hashimoto's.
High estrogen, parasites, protozoa, and pathogenic bacteria can contribute to gut problems. If you want to test for parasites, protozoa, and bacteria, there are two labs in the U.S. that do comprehensive testing for this. I used the Parasitology Center in AZ.
Fluoride suppresses the thyroid, so if you have fluoridated water or toothpaste you might want to switch. Also, gluten confuses the thyroid. Hydrogenated oils (trans fats) contribute to heart issues and high blood pressure. (See the documentary Ingreedients). Also, eating aronia berries prompts the body to make glutathione, which helps the body heal itself.
Lyme, its co-infections, and mycoplasma can also cause heart palpitations, and more specifically a pericardial effusion, a mitral valve prolapse, and a partial right bundle branch block.
I'm dealing with a number of these things personally, so I thought I'd add my two cents. Best wishes on your journey toward health!
