Fluid Blister near TT incision... (photos)

No need to worry at all. Besides, you will be seeing your PS in another day and he will surely put all your doubts to rest. All the best.

Your photo appears to demonstrate a small skin blister.  These can occur due to traction on the skin caused by tape or steri-strips.  In the absence of other wound healing concerns, I believe you are fine to wait and address this with your surgeon at next appointment.   

Congratulations on your surgery and wish you a speedy recovery.  The small fluid blister is nothing to worry about and can wait until your follow up appointment. It may burst before that and that's ok.

Hello and thank you for posting your question. Blisters form after many plastic surgery operations as a result of skin stretching due to swelling and the steri strip tape that is placed at the time of the operation. If the skin beneath stretches more than the tape strip itself, a blister may form. The good news is that this is usually temporary and the area heals without issues. You may experience a little drainage if the blister pops or some superficial skin peeling in the area if your swelling was significant. I would certainly show this area to your plastic surgeon and allow them to examine you and give their recommendations.

Always ask your plastic surgeon for a definitive answer but this appears to be a superficial blister from the steri-strips.  When the skin swells the steri-strips can pull causing a traction blister on the skin.  If the blood supply to the skin is adequate, this will heal without problems.
