In general you should try to avoid popping a blister if possible. However, the ultimate decision will depend on the size and location of the fluid bubble, and whether or not you have any other health issues that might affect your body’s sensation and natural healing processes.
If you have diabetes, never attempt to pop or drain a blister yourself, as the risk of infection is very high and can lead to profound consequences (even amputation) if untreated. Keep the skin intact or have a doctor drain it for you. The area should be protected with a bandage and left alone, unless it is actually causing you pain or in a difficult location. In that case, we can instruct you how to clean the area and carefully drain the fluid by making small perforations in the edge of the bubble with a sterilized needle.
