I got some blisters on my toes, and I poked them with my hand.

It is best not to use your own hand to puncture blisters on your feet, which is prone to infection; if it has been punctured, you can use iodophor to disinfect the local area, and you can also apply some anti-inflammatory ointment such as erythromycin to prevent infection. Pay attention to maintaining local cleanliness at ordinary times to reduce local irritation.
