Suggest Treatment For Cellulitis In Lower Leg

Hi,
Ihave celulitis in both my lower legs, my left leg appears more swollen and warm. This is my second week on atibiotics, plus penicillin vk. My legs are still stinging and also experiencing a numb feeling specially in my left leg. My left leg also had pain at the top of the leg and theigh feels like my leg was going from underneath me when i walk for a period of time. I have taken ibuprofen and this seems to have done the trick. Iam concerned as i feel the antibiotic doesnt seem to be working. Can you give me some advice please. Thanks A Ryder
