I know this sounds gross BUT(no pun intended) for the first time in my life since I have moved to Thailand which is very hot and humid and I have started to get red bumps on my butt,lower back and sometimes on my legs.In America I have never been affected by mosquitoes in my life,I have never had one single red mark or itch from a bite.Do mosquitoes in different countries give different allergic reactions that could cause this or it is the extreme heat and humidity?I did notice when sleeping in a bungalow without a bug net I had many the next day but I still get them in my house without(as far as I know)any mosquitoes.HELP!
