Save Mom's Foot: Urgent Medical Help Needed

I seriously truly hate to do this but we are in dire need of a test to be done to my mom to see if her foot can be saved and unfortunately it’s not much cheaper in Mexico like we had hoped and thought for her to get seen. On top of that as well she is being prescribed a lot more medications. Please if any of my friends or family could kindly help out with anything, anything at all, it would be greatly appreciated and wouldn’t go unnoticed thank you all so much in advance
