BTDT myself. Mine started with Type I diabetes several years ago. Then add the Hashimotos.
Then in 20111 add in Shingles, which caused Viral Meningitis. Since then I have been diagnosed with Celiac disease last year, and (this year finally!) with Fibro and now Lupus. My symptoms were very similar to yours.
While I was trying to find a dr who didnt say it was either all in my head or it was hormones, I did a little of my own investigating.
If you are on a statin drug you may want to add some COQ10. I also added in B12 and Vitamin D. That helped a great deal, and I also cut out sugar and caffeine from my diet. Then I eliminated anything processed and anything in a box (except for Special K cereal and the occasional taco shell).
Being very careful what i eat, to a fault, has a direct correlation with how i feel. If I am not super careful and eat something i shouldnt, I pay dearly for it the next day and sometimes into the second day with joint and muscle pain and all sorts of agonies. I also learned that inflammation in your body feeds on sugar, so the less you feed it the better you feel. You will have to find what foods are triggers for you and what aggravates your conditions and what doesn't.
For me between the celiac, the fibro, the diabetes and the lupus it was just easier to cut it all out and pretty much just only eat food in it’s natural state and nothing from a box.
About 6 weeks ago my rheumy put me on Cymbalta and Gabapentin and I feel so much better. I will never be back to my old self again but I can actually go ride my horse and not spend the rest of the day in bed.
