I Am 50 Yrs Old, My Labs Are Good. I

I am 50 yrs old, my labs are good. I have chronic fatigue, year round allergies, my eye sight fluctuates{, my ears ring possibly due chronic tonsillitis and ear infections as a kid and i have mild dizziness when active. { gymnatics, tumbling and dance classes{ I also have itching, mostly in my hair, scalp and around my face and neck. Not bad itching, just like I have been dusted with itchiness...for lack of better words. I am celiac, no DM. My doctor's have told me over the years, it is just me and my body. what are some possibilites?
