Extreme pain after taking hit?

I woke up this morning and decided to have a smoke session after picking up some fire bud last night, when I was smoking it, I took my hit, held it in, and at this point all was good. But the second I started coughing I was instantly hit with this intense, might I say extreme pain directly to the side of my right eye socket. On my first cough, which was extremely harsh from my bong, I swear I could almost feel this ripping/tearing feeling in my head before the pain started. The pain is akin to a headache/being hit in the head aching. Like it feels like a headache, but it's also throbbing like I was hit with something. This doesn't seem to happen whenever I smoke. Only once in a blue moon. And for some reason it only seems to happen when I'm smoking from my bong which ALWAYS tastes just absolutely terrible and bitter and I can't figure out why.

 

That's what I'm actually starting to think it is. It doesn't feel like a normal headache.
