I am sorry Nini is having discomfort around her rectum. The anal glands sit right inside the rectum and can become inflamed and rupture. However there are also peri anal fistulas and growth that can have the same appearance. I would not recommend giving her half of the cephalexin. This is still to high of a dose for her and can cause vomiting and diarrhea. I would recommend not giving any type of antibiotic until Nini see's a vet for a good exam an to determine the exact cause of the lump area. You can try to do warm compressed two times a day. Also you can try an anti histamine to help decrease inflammation. I hope Nini starts to feel better soon
