Best treatment for ringworm

[PJ67]

Hi. My 14 yr old son has had ringworm in the palm and side of his hand for ages and nothing seems to be clearing it. He has tried terbinafine, ketoconozole and miconozole but it still seems to be spreading. Seeing the dermatologist again at the end of June but wondered if anyone found one cream or treatment that worked better than the others.
Thanks

I got it some years back. Mother said I'd caught it from the cats. Told me to use Tea Tree oil and it worked. I could literally taste it in my mouth, but it never returned.

wash your infected area with water and soap. Apply antibacterial cream along the border of the infected area.
Follow this procedure for a week and if you still face the problem then visit doctor.

Thanks. Are you suggesting antibacterial rather than anti fungal cream Patrick?
