Hi, My name isXXXXX you for using Just Answer. I am another expert with some additional information for you.
It wasn't mentioned in your post, so I am going to suggest she be on an Anti-Inflammatory medication, if she is not. This should be taken on a regular basis to get its full effect. I suggest Mobic 7.5 mg twice daily (generic is Meloxicam) This is a prescription, so this will need to be discussed with her doctor. If you do not want a prescription, over the counter ibuprofen can be taken. She can take 200mg three times a day with food.
There is also a book that can be purchased on amazon that talks about foods/vitamins that can promote healing. I will attach the link for you.
Copper is essential in healthy connective tissue and bones. Crimini mushrooms are a great source of copper. A low copper level can actually prolong healing.
Vitamin C helps with collagen production which can help with scar tissue. It can be found in bell peppers, strawberries, citrus fruit and broccoli.
I hope this additional information has helped. If you have any further questions please let me know. I hope you daughter gets better soon. Have a great day and a Happy New Year.
