Don't worry your mum will be fine just advice her not to do strenuous chores or work that will make her injure herself because if she is wounded that wound will spread over that area and become gangrenous if medical intervention is not given early.

Also advise her to take lots of vegetables in her meals and avoid too much sugary or salty meals but she can take it in a little quantity if she wish. Encourage your mum to visits her doctor regularly, not once in a while because this will go along way to improve her health and wellness. My regards to your mum.
