H/a again x3 days.extremely fatigued even w/sleep.whole body aches and hard time focusing my vision. no dr appt til next wk. no otc meds help no fever?

Rest and water: Drink lots of water, tea (lemon and honey) - rest a lot, eat lightly as often as you wish until the appt. Massage or accupressure may help. Stay warm and do non-stressful activities. Could be a bad viral thing but next week will tell. Best!

You need to be seen: There is a long list of causes. It will be hard to give a simple answer without an exam and detailed history. Make sure you are well hydrated, and seek help sooner.
