Certain people build massive scar tissue.
Incision wise, when the proper time comes.. gentle massaging and possible vitamin E and Aloe are good for this. And my rehab therapist.. she put a breast pump onto my back and used that to gently pull the skin around the incisions. She told me was gonna do something that "sounded quite unconventional" and she was right! BUT IT WORKED AMAZINGLY WELL! Took the stiffness right away!
I am not one that builds scar tissue as a norm, but still I feel very little if any around the incisions and I have 6 of them.. and it's been over 9 months now.
Internally, our bodies go into overdrive to protect and thus scar tissue forms. And for some, it's ALOT! And it often causes problems, especially when it happens near nerves.
I was told that stretching.. the foot flexing your doctor mentioned, is the best resource to help reduce or prohibit scar tissue from forming there. So stretch and walk, walk, walk, and then walk some more! It really does help!
All the best to you! Tammy
