Brief Answer:
Herpes simplex or paedrous dermatitis, answer few questions

Detailed Answer:
Thanks for being at Healthcaremagic
I have gone through complaints and reviewed the attached photograph.
It seems to be either herpes simplex infection which is a viral infection or paedrous dermatitis which is a reaction to bite or crawling of an insect.
I need to ask you few questions:
What is the duration of blisters?
Is this the first episode?
What is the site of blisters?
Kindly revert with the answers.

Symptoms started showing two days ago was just an area on my arm that felt stinging and burning sensations. Then yesterday I noticed that a cluster of blisters had started showing. Today the area became more raccoons and the blisters became more intense as well as the burning pain .

Brief Answer:
Herpes, oral aciclovir & topical antibiotic

Detailed Answer:
According to your complaints it looks like herpes simplex.
If I was your treating doctor I would recommend you to take oral antiviral medicines like tablet aciclovir 400 mg thrice daily for 5 days and apply topical antibiotic like mupirocin cream on the affected areas twice daily.
These are prescription drugs and you need to see the doctor in person to get them.
