 [ Symptoms ] when i dont eat for more than 3 hours i shake get hot flashes and pass out my sugar levels are normal when checked uptaking sugar when this happens was my doctors advice but it does not always help if i do not eat within ten minutes of this shaking and hot flashing then i pass out for over an hour my blood pressure is lower and so is my pulse my daily resting rate is 10471 and hr of 58 65 neither of which my physician was concerned with my temperature runs in the normal from 96 97 f shaking intensifies if i use my muscles when resting i fell no shaking only if i move  why [ Disease ] i am sorry to hear your mother in law is going through this but i am glad she had glaucoma ruled out severe eye pain should not be ignored eye pain generally is not a symptom of age related macular degeneration i would suggest your mother in law make an appointment to see an ophthalmologist as distinct from an optometrist to have this evaluated an ophthalmologist is a medical doctor md who is specially trained to deal with high level eye problems such as trauma glaucoma and other serious eye diseases i wish you both all the best
