Hi there ~
I understand your concerns. I am thinking that the indentation in your oblique is something that you do not need to be worried about. It will get better over time. Supplements of microminerals and multivitamins will help in the healing process, especially vitamin C
. I hope you are getting enough of those. I also think that rest as you have been getting for the last few weeks and adequate sleep will also help in the healing process. If you feel like the indentations is serious and may indicate a physical abnormality, please consult a qualified doctor.
I hope this helps. Take care and have a lovely day!
