It is possible that it is a local reaction from a bite or a sting, but I would also worry about it being a skin tumor. Mast cell tumors or histiocytomas can have that same appearance. Do not squeeze it or irritate it much as it can cause it to spread if it is a mast cell tumor. You can apply cortisone cream to help with the redness tonight, but it will need to be checked by your vet to find out for sure what it is. It is rare that it will rupture in a short time frame, so I would not worry about that.
