I Have Burnt On Holiday At First It Was Sore

I have burnt on holiday at first it was sore and then started to calm and brown I woke up this morning with horrible lumpy blisters on my shoulders and top of my arm.... One on top of my arm has popped and about a 1cm round the skin has fallen of with it what can I use to treat, will aloe be ok? Also some of the smaller ones are leaking yellow fluid... They are not painful just an eyesore ! The popped one is stinging ? Please help me I don't want it to ruin my holiday and also don't have 100pounds to go to the private doctor here.
