Will this TT blister heal on its own? Worried (Photo)

Hello, usually blisters caused by tension from an overlying dressing are superficial and will go on to heal.  However, your physician would need to do a proper assessment to get a better sense of the depth of injury.  They will also be able to provide specific instructions about wound care, since keeping it covered and clean will likely decrease the chance of infection.  

Those areas look like they should heal.  Keep moist with ointment of some sort and avoid excess heat or cold or really tight pressure.  But definitely call your surgeon, I'm sure they will be happy to look at it.  Jane

There does appear to be partial thickness skin injury, worse on one side than the other. The shallower looks on its way to healing. The deeper one, while may heal after a longer period of time without issue, should be seen by your surgeon so the best treatment can be recommended.
