id like to know the answer to that also because ever since i moved to a hotter climate iv had a rash on chest and back and i think its prickly heat rash because i sweat alot more now but iv had it for almost a year!!!
Hello,
Yes prickly heat or malaria can last for months.It is common for milaria to occur when people travel to a warmer climate and sweat more than usual. In most cases the rash will clear without any treatment. However, severe cases can last for several weeks to months.
I hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
