Accidentally strained 11 days post facelift, advice?

Hi there and thanks for your question.  The biggest worry with any injury after a facelift is a hematoma, which is a collection of blood under the skin.  In this case, the blood may need to be drained from the face.  However, after 11 days everything should be healing nicely.  If you see or feel any changes, I suggest following up with your plastic surgeon.  Best of luck and feel better! 

From your description of the straining event you had 11 days after your facelift, I doubt that any damage was done.  If you are feeling fine and there was no worsening in your appearance, you should be fine.  

Without any signs of swelling, pain, or asymmetry, it is unlikely that you caused any harm.  It's always a good rule to stay in close contact with your surgeon.  My patients have an open and direct line of communication with me (cell and email), which we pride ourselves on.  Good luck moving forward!
