I'm sorry your cat is having this problem. It is very possible that stress triggered this obsessive compulsive action. Once it starts, the inflammation there makes it sore so that continued licking is more likely: a vicious cycle so to speak. There are a few things you can try at home to see if you can resolve the issue.
I would try topical 1% hydrocortisone cream applied in trace amounts to the site every 12 hours to reduce the inflammation: make sure hydrocortisone is the only active ingredient in the product you use. Distract Jazzy for 5 minutes after application to give the cream time to work. If that hasn't helped after a few days, then I would try topical lidocaine cream two to three times daily (again, only active ingredient in the cream is to be lidocaine/ spray is not recommended). Five minutes distraction after application of the lidocaine is necessary to allow it to work. If both those fail, then you can try Bitter Orange which tastes bad and may deter your kitty from licking. Finally, an e-collar may be necessary to break the habit: http://www.amazon.com/gp/product/B00Y2TL4EQ?ref_=zg_bs_2975292011_15
Ultimately, if the problem persists, a trip to Jazzy's veterinarian is wise. She may have caused an infection at the site that will require oral/injectable antibiotics. Of course, they will also examine her fully to be sure there is no other reason why she may be licking the site incessantly. Rarely oral antihistamines or steroids may be needed for such a problem too but seeing the vet is necessary to determine that.
