Thanks for contacting us about your mum. Sounds like she is quite troubled by the symptoms in her foot.
Dr Ethan has provided a excellent synopsis of the various causes and treatments available for metatarsalgia. This is probably one of the most common causes for foot pain and can be troublesome to treat.
However, pain under the ball of the foot can be caused by other issues. There can be soft tissue bruising from trauma, a bony injury from an acute or stress event, swelling around nerves, tendon issues and so on.
Further questions to ask are about tingling in the foot, onset of the symptoms and progression. These can all give clues to the underlying problems and how to address it.
Simple measures could be wearing comfortable slippers or shoes in the house – often with barefoot living on hard flooring, the symptoms are not given a chance to settle.
I would certainly try the treatments suggested by Dr Ethan – particularly a course of anti-inflammatories if there are no allergies or issues with these medications.
If it’s affecting her mobility, it might be worth reviewing with a Podiatrist or clinician for further assessment, investigation or consideration of orthoses.
Foot pain can be incredibly frustrating, but the important thing is to work out what’s going wrong before moving forward. Hope this all helps your mum and do keep us posted!
