I enjoyed this video it was broken down so that anyone could understand. I have a wound that has taken along time to healing I learnt that my age and diet has contributed for the length of time. So I have to make some changes. Thanks

[rekanapsugar]

Fantastic video thank you so much for taking the time to explain things with such patience and clarity ❤

[udiorockmeamadeus]

Thanks!I have a question: is there astandard for how to recognize antibiotic from somethng that isnt, like are all antibiotic tubes ointments, and seeing a cream would tell you this is not to be used for wounds? Are there any standards in the healthcare industry like that to identify fromm afar if someone is using the wrong equipment or drugs, application medium, etc..

Thank you for this. Would Healing 101 was the first video from your channel that I watched and found that it's the best one on the topic - in dept enough to be very useful but not too hard to understand for general citizen like me. Would Closure - All Types Explained was another video from you that I really like, and I found this one fascinating. ☺

As a Healthcare professional, I thoroughly enjoyed this vedio and will be watching your channel for more. Keep up the excellent work 😊

[Mrjack]

I asked 5 different physicians for help with my non healing wound before I made a suggestion and got the help I needed. My wounds are healed now with visits to a wound specialist (which are hard to find)

[rightpa]

I always remind patients that a little redness around the wound is normal. Fire engine red with increasing pain is bad news. Even then a lot of patients think that even the normal erythema around a wound is infection.

I am a CWON./RN Finding your videos very relevant, helpful and informative. t.y.

I would like to hear what you think of ultra misting and placenta grafts. Also, about hypergranulation and what you use for that to heal. Do you like using Adaptec on wounds, blastx, and Mupiricin?
I'm a bilateral amputee who has had 8 surgeries and mrsa and psudamonous infections in just the last 2 years. Oh, also, i have Scleroderma.
Thank you for your expertise.

I have skin graft wound, I’m taking antibiotics now but still red and open, what do I eat and how do I clean and sanitize?what medicine should I put

[JonEyv]

Apart from the moisture apparently wound needs to breath so it's to user a layer that keeps moisture but let's some air / moisture to get out

Hello, my name is Shawney crow, I have a wound since 2019, my abdominal above my belly button. Let me start from the beginning, I have had 7 hernias, the last one doctor had to pull some of my muscles from my back to repair the hernia, same size as a football, ok days later I'm at home healing, went one of the staples came lose only hanging on by skin. Called the doctor went he took out the staples. A week later at home I saw where the staple was at had gotten bigger called the doctor went in and he cleaned it and said clean this everyday and put a bandaid on it. But then after that a another week later it started draining and had a smell to it, like poop, nasty, and yellow and brown. Really thick draining. And now it has gotten bigger hole. Now the doctor said clean it everyday and a dry wet dressing, even had me on a woundvac everyday. Went back for a check up, the doc said need to go in and put a another hole to help it heal and drain better. Did that and now still I have 2 holes in my abdominal, still the drainage looks dark pusy and has a dead person smell, and still to this day all they do when I go see a specialist they undress it, clean it measure and take pics and redress it, that's all. They haven't done any x-rays or talk about how we going to heal it. At one time I had mersa, what they do when I go to wound care, I can do here at my house and I have. They won't go in and find out what is causing this to fix it, I have been living with this 6 years now. I can't get up and move around and use my stomach like I use to. So I have gained a lot of weight, never have I ever been this big b4 and I really miss working out.

I have a wound same as the picture, a little deeper...what hospital do you work at..how do I contact you

[gieslerbrad]

Do you have an opinion as to what the best wound dressing for an injection drug user to put over their injection site, if anything? The only information I can find is “keep it clean” but I’m wondering if there are things IDUs can do to not only avoid infection but also prevent scar tissue and vein collapse.

QUESTION: How is it possible for intestinal ulcerations associated with Inflammatory Bowel Disease to heal if treatment continues uninterrupted irrespective of inflammatory markers? The insertion of bioactive wound dressings that have been tried for ulceration do not seem to be offered presently (where I live).

[carathorsven]

Herbalist assess tissues based on temperature, moisture and tone. I think this is much more accessable to the average person. Temperature as applies to wounds would be, is it hot and inflamed? Or is it lacking curculation, purple and blue, black colors.
Moisture is obvious, is it dry and flakey and scabbed or is it wet, weeping, slimy.
Tone, is the skin tight and inflexible, or is it sagging and loose?
Amazingly enough when you balance the temperature, moisture and tone, you avoid and eliminate infection by making the body inhospitable to pathogens.
Systematic factors are also very important to adress. The roots of health, food, water and oil, breath, excercise, mental emotional spiritual wellbeing AS WELL AS the temperature moisture and tone of the over all constitution of the body.
