funny reading this the read. years ago (age 65ish) I started getting changing conditions. hair falling out, thyroid up then down, stomach pains with gerd, painful gas with constipation then the opposite. sneezing every day, no alergy. blood work normal, stomach fine, drank more water, changed thyroid meds. everything worked, just changed what bothered me. Dr said it was just that I was just getting older.
I was always so healthy that I commented to my doctor that I thought it was something systemic.
Fast forward to age 74 when I got my colonoscopy and it was found that I have stage 2 anal cancer. can take years to develope.
I guess what I am saying is don't let doctors stop by giving you pills. see if they will give you a petscan.
find out the base reason for your illnesses. they may be connected to something you can nip in the bud.
