Terrible Headache and Pain

Make sure you have eaten something. Doesn't have to be much. Just something your stomach can use its acid to deal with instead of churning at nothing. Also make sure you have been staying hydrated. Dehydration can really mess with your body. I am very guilty of that. A cool rag to the eyes and head can help with inflammation. Maybe try black noise or brown noise to help dampen some of the sounds around you. Sunglasses are also really helpful for over stimulation from light. I hope this helps.
