Yes all up about 7-10 days for patches associated with a longer term infection.
I don't quite understand what you mean fleetwood, sorry. When you say start with a red patch with a blister then ulceration 7-10 days. Is that 7-10 days from start to finish from day 1.?
It would be very likely that you'd experience a small outbreak. It's likely though that the same process and timeframe is involved. Little raised red patch perhaps a blister or two inside lasting a few days then ulcerating perhaps with a scab and proceeding to fresh skin by 7-10 days.
