I Have Cellulitis On My Right Leg. I Had A

I have Cellulitis on my right leg. i had a fall and this developed. The fall was 9 days ago. I have been on Keflex for 500 for 4 days. The bruising and swelling had diminished. I still have a big hard place where I fell, this is just below the knee. My concern is I still have pain and wondering if this just takes time? cant get in to see my Dr.
