I went to sleep, everything was fine. i wake up this morning & my left eye, only my left eye, is burning & watering like crazy. how can i get relief.? i can't afford to go to the doctor.

Needs examination: an acute eye, as what you described, needs to be examined, if you can't afford a a doctor, you want to go to ER, but don't wait on it, good luck

Well: When it comes to eyes you are always better to be checked out. Now go see your doctor and get that eye examined and treated

Need to be seen: You need to be seen by a MD or a helath provider to make sure no corneal abrasion or other issue with your eye best for you is to go to Urgent care or ER
