Hi since last week my left eye is hurting every morning and i have to take pain killers to get better if i don't take the pain stays until i take them?

Would: Definitely see your doctor. Could be a primary ocular problem, migraine or cluster headache or nothing, but hard to tell without examining you.

Number of possibles: Regardless of what the cause is, you should get checked. Your pain could be anything from migraines to sinus infections to eye issues. Again, don't treat yourself and get checked by a physician as soon as you can. Good luck.

See Eye Doctor: Rather than mask your pain with pain meds find out why you are hurting and see if there is a real treatment for it. In the short term using pain meds until you figure this out might be ok. In the long term, it will be a big problem as you may develop tolerance requiring higher doses of meds, dependence to them and even worsening pain if you get on higher doses like hyperalgesia.
