Almost 6 Months Post-op. How Likely is It to Damage the MR in a TT?

It is unlikely that you did any damage to your muscles six months out, but when in doubt check in with your plastic surgeon.  Most of the healing between the muscles takes place within the first 2 months.  Even so, the abdominal wall which has been tightened will respond to and be modified by the tension it feels for a number of months after surgery. The tight tummy will eventually relax somewhat and find equilibrium.

With your degree of excercise the degree of soreness sound normal and your surgeons plan seems reasonable, but I would have you check in just in case.

After 6 months, most of the healing has completed and durability restored to the entire abdomen. There may be additional softening and fading in your scars, and of course there may be more sensation as cutaneous nerves heal and regenerate, but the muscle repair has reached a point that any kind of exercise is safe and appropriate. . .

 . . . as long as you start gradually and slowly build up intensity, especially after NO exercising to that extent since before surgery.

Realize that even professional athletes can tear muscles, rupture tendons, and cause themselves injury by over-doing a certain exercise or activity. So can you. "Listen" to your body and build up your exercise routine more gradually.

It is actually extremely unlikely that you did anything other than over-exert your out-of-condition abdominal musculature. Soreness is the normal response. Tearing of sutures and all your healed scar tissue is possible, but extremely unlikely. So, take ibuprofen, relax, and see your surgeon IF symptoms persist.

I'd bet that things will settle down if you give yourself the time and avoid re-injury by overdoing it. Best wishes!

Thank you for the question.

At your stage,  I think it would be extremely unlikely that you have done any damage despite an intense cross fit workout.   Usually, if this does, occur that are associated  signs or symptoms ( such as a honorable “snap”,  swelling/reading/bruising  or new onset bulging....).

On the other hand, I think your body  is probably telling you to “slow down” ( hold off on the "burpees"  for a while).

I would suggest a period of  rest ( at least a week), the use of anti-inflammatories and follow-up with your plastic surgeon if the discomfort continues and/or if there's any change in your physical examination. 

Best wishes.
