BCC forehead focal perineural invasion pt3 nerve

Hello this is my first post. I have had a leison on my forehead for about 4-5 years and past GP's have given antibiotic cream to help it but it never healed. In December I was sent by a new GP for 2ww to dermatology and had a biopsy which came back benign. I had a dermatologist appointment 4 weeks later and thats where I was told it was BCC and I would need a wide excision. I had that 3 weeks later. On Wednesday I got my results and was told it had all been removed but I had focal perineural invasion is noted pt3 nerve diameter 0.1mm bcc. My consultant said the treatment would be radiotherapy but because of my age (44) they will not do this and I will have to just keep an eye on it. That has made me worry that it has progressed and I have to just leave it. Now I'm very poorly at the moment and my excision wound is infected, I have a massive coldsore, fatigue is horrible and have bad headaches. I know this might be my body just needing rest but also scared its to do with my aggressive BCC.
