Pericorinitis most likely,..or perhaps you have a bombed out tooth back there as well.
Extractions are ok and fear and anxiety are completely normal. But they all can be conquered if you are willing to get out of pain and take things at a pace you are comfortable with.

your choices to deal with anxiety and fear are
1) nitrous - laughing gas, is cheap, and safe, you'll feel stuff but you just won't care.
2) conscious sedation - take some pills, fall asleep, wake up with one less tooth, still in pain b/c of the residual infection, but you will heal and get better
3) general anesthesia - put out completely, don't recommend this, too risky for little benefit.

but the biggest thing is to find a guy that you can trust, who is gentle, and is willing to explain everything, and go at your own pace. you should feel no pain during the extraction, but perhaps a little bit of pressure. that's it. you should accept nothing less than that.

GOod luck.
