We got quacks everywhere, some sew like they are sewing a bag or a non living thing, I would share an experience when i involved in a fight with someone, my lips was torn as a result of a blow from my opponent. I was surprised and scared at which my lip was deeply torn.
The picture of it made me scared and anxious and I went ahead to sew it. Since it was a fresh wound on the lips, the person sewing it couldn't see vividly the right paths to sew and he did it with much pressure tightening the threads and this job was done in the night that same day i had the fight.
NOTE: This advise also goes for other parts of the body.
I WANT TO GIVE AN ADVICE, ESPECIALLY FOR THE LIPS
If you got a deep cut on the lips don't just into action to start sewing the lips, wait till the next day so you can know exactly the severity before you take the action of sewing. It is practically done in Medicine to have an injury today and sew the next day most especially for lips.
Though the lips is a very sensitive part of the body and your enemy would want to get you there to demoralize you during a fight if you are not a good blocker. But the fact remains that the lip has so many sub capillaries and networks of arteries connected to it, it wouldn't be the best decision to start sewing it when an injury occurs that same day, because the sewing would block and disorganize the networks of these arteries after the injury might have gone and it's gonna cause you some discomfort, as it is advised that the lips heals fast, vitamin C could help in facilitating it's healing.
SO DON'T RUSH INTO ACTION SEWING YOUR BODY PARTS OR YOU GONNA END UP REGRETTING THE THICK SCARS WHICH COMES WITH SOME FEELING.
IF YOU GOT SUCH CASE, WHAT COULD HELP WOULD BE A REVISION SURGERY BY A PROFESSIONAL IN THE FIELD.
