I had my WLE on January 17th and they patched me up on January 31st (scalp reconstruction and rotation, 55 staples). The wound opened up when the staples were removed and I have posted about it on here before.
About 3 weeks ago my scalp kinda hit a plateau. It just wasn't healing anymore, or had slowed considerably. A week went by and the wound really had not changed at all and was still leaking and bleeding.
Around 9 days ago I started lifting weights again, properly with no restrictions. And since then it's like the healing went really quickly. I went from a hole in my head to almost closed and the skin that has formed has feeling and sensation too. I expect it to be fully closed in the coming days.
I also found a paper from 2008 by the NIH that states exercise accelerates cutaneous wound healing in mice, so it may not be my imagination at all. https://www.ncbi.nlm.nih.gov/pubmed/18003791
Hopefully this helps someone.
