air it out son. did you get sunburn as well as road rash? Sometimes a sunburn will do this when you sweat. small blisters that will fill up. Check your temp. See a spike hit the docs office. I'd give them a call to the hotline and see if you'd need to come in as is most likely just something minor.
Tegaderm for later . Not sure if you can order from these guys without a provider number or not but it's worth a shot. Could get your local EMS/Fire department to order it if you paid them up front.
