Husband and I are just home from a European holiday, where we got loads of bites. This is not unusual for me and i had supplies of creams etc to use while there. Hoever, these bites were different from any others i have seen. They form blisters shaped like round balls, raised up above the skin. What are they? All healing nicely now.
Are you sure you haven't got chickenpox? Its the blister on the spots that make me think that.You can get it more than once , i have had twice and know other people who have.
It's not unusual for nasty insect bites to blister - I've had lots of them! So long as they continue to heal & don't show any sign of infection (open sores with weeping) you'll be ok.
If you're worried ask your pharmacist for advice.
