went camping and now i have blisters

so I went camping and one day after hiking I noticed raised red bumps. I thought they were really bad mosquito bites the next day I woke up they turned into blisters with redness around the blister. I washed the area gently with soap and water just in case I had something on my skin that made it like that. yesterday night i put tooth paste on the blisters as toothpaste usually dries up blisters byoday the redness around the blisters are gone, but the blisters aren't gone. I'm sure they'll go away on their own as it seems to be getting better, if not I will go to the doctors but has anybody had this happen to them or do you know what could if caused this? (there was no itchiness or pain btw)
