I traveled to Honduras & Belize on a humanitarian trip visiting schools. Before that, I traveled to Mexico on a short 3-4 day cruise, where we ate the local food. I have Hashimoto s Thyroiditis, but all levels are ok. I m extremely fatigued, back pain (although, yrs. Ago I had an ependymoma @ L1-2 & radiation, however, I never experienced back pain, just leg), also memory loss, & joint pain. Any ideas?
