If a blister arises after treatment at our office, we recommend a prompt follow-up appointment depending on the severity. If the blister increases in size, has blood present or is red/swollen/draining, you should call the office to be seen. In the mean time, no at-home treatments should be used to reduce further aggrevation at the site. If the blister does not have the above symptoms but remains bothersome and slightly painful, also discontinue at-home remedies until blister resolves.
