Are these my internal sutures snapping?

Hi.  I tell patients not to turn their head too much for the first 6 weeks after facelift surgery to prevent sutures in the muscle layer from tearing.  I tell patients that they can turn until it feels tight.  I recommend that they turn at their waist more than at the neck.  

3 1/2 weeks is still in the initial stages of the healing process following a facelift. It is not uncommon to have all sorts of strange sensations at this stage of healing. Typically, by 3 1/2 weeks the muscle layer will already be partially scarred down and providing some strength to the lift meaning that the sutures are not doing all of the work. It may also be scar tissue forming in the neck as well. If you appear to be healing normally I would not be too concerned about it. Regardless, you would need to wait several months to have any revision work. Make sure that you follow up with your surgeon so that he or she can closely evaluate and make sure there is nothing that needs urgent attention.
