Efudex, skin cancer and rosacea

I had a little red spot on my face appearing to be skin cancer, which I have had and treated (with Efudex) on my arms and legs. I applied Efudex, and discovered a couple more red spots appeared next to the spot. So I smeared Efudex all over my face to see if there were more--and there were ... many more. However, I have a mild case of rosacea, and the rosacea area swelled and scabbed and is very painful. Metrogel causes more pain. Alovera and ice packs help, and I am using coconut oil. What to do? Also, some of the skin cancers that were discovered are on my lips, and they are blistered. What should I do?
