Thanks for posting your querry.
After reading your symptoms i feel that you have developed itching due to bed bug bites. Such infections cause pain, itching as well as burning sensation which you have mentioned.
I would recommend you to take a strong anti allergic drug, it will make you feel better soon. You must also apply calamine
vira lotion on the sites where itchi9ng is maximum.
If you do not feel better after the antiallergic then you must visit a dermatologist
for clinical examination.
Hope you feel better soon.
