Hey Zombelina --
There does seem to be a connection between some kinds of epilepsy and autoimmune disorders. And fibromyalgia can have similar systems or co-appear with autoimmune disorders like rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), polymyalgia rheumatica, or another inflammatory or autoimmune disorder. So there may well be a link.
I hope an anti-inflammatory diet will help. Below are some general suggestions for treating auto-immune symptoms (consult your doc, of course).
1. Check for hidden infections — yeast, viruses, bacteria, Lyme, etc. — with the help of a doctor, and treat them.
2. Check for hidden food allergens with IgG food testing or or an elimination diet.
3. Get tested for celiac disease.
4. Get checked for heavy metal toxicity. Mercury and other metals can cause autoimmunity.
5. Fix your gut -- nutrients such as fish oil, vitamin C, vitamin D, and probiotics can potentially help calm your immune response.
6. Exercise regularly — it’s a natural anti-inflammatory. With your back pain, non weight-bearing exercises (like some kinds of swimming) might be worth a try.
7. Practice relaxation techniques like yoga, meditation, and deep (diaphragmatic) breathing. (Stress makes the immune response worse).
Good luck!
