What kind of bug bite do I have and can it be dangerous? (in india)

No idea. Where is the bite? What does it look like? Painful? Red? Seek help from someone who knows the bugs there. India is known for homeopathic medicine and you can certainly benefit from a trained homeopath there. Rub a slice of onion on the bite. It neutralizes the toxin reduces swelling and itching etc. If it worsens or you are worried, you need to be seen by someone.
