Thanks for tip guys. To answer some questions, yes my ENT doc and I are considering surgery. The CT scan showed some kind of a build up in my sinus underneath the left eye, and it could very well be a cyst (which explains why antibiotics aren't working).

I used Sudafed for a while as a decongestant and saline nasal spray to clean my nasal passage, but I stopped because they weren't helping my condition (constant wooziness). I am however taking Nasacort AQ steoroid spray to reduce the swelling of my nasal tissue. Oh and I did have a deviated septum but I got that fixed few years ago.

I have an appintment with my ENT doc again next week...I think I'll try to convince him to authorize a surgery because I'm sick of taking antibiotics.
