What could be causing stabbing/aching pain behind my right eye? the pain is not constant, it comes and goes. i have been having it off and on for weeks. i read that large, unruptured aneurysms can cause eye pain. but would that be a constant pain?

If you have eye pain, see an ophthalmologist to evaluate entities such as glaucoma. Would be amazed if an aneurysm could be the cause of your symptoms. Stop seeking alternative opinions and instead get an expert to assess.

As in another response, please see an eye doc ASAP. Please don't let your mind run away w/you. There are lots of possibilities. One is cluster headaches, a form of migraine. Peace and good health.

Commonly sinus or migraine problem. See your medical Md and he will refer to specialist if necessary.
