Hello,
Most common causes of blisters could range from sin burns to mild bacterial infection. I personally advise for simple remedies:
1. Kindly use Lactocalamine lotion as many times as possible
2. Change footwear sometimes due to friction it may lead to this.
3. Do NOT prick or remove by puncturing it may lead to spread of infection.
4. Try mild antibiotics like
Augmentin twice daily for 5 days
5. Usually these measures will heal the affected area.
In case it doesn't heal, repeated blisters at other areas, pain, pus discharge kindly visit a
dermatologist to rule out other causes by asking you to perform blood tests and give the suitable drug.
Hope I have answered your query. Let me know if I can assist you further.
Take care
