How can I get rid of foot pain on walking?

I think the most important thing to answer is, what is the cause of your foot pain. We need to find the root problem and aim towards managing that. There are many many causes of foot pain, with plantar fasciitis being the most common.

We would need to examine your foot and ankle thoroughly and do some radiological investigations like an X-ray, Ultrasound or even an MRI (depending on what pathology is suspected). Treatment modalities can then be done, ranging from non-surgical options like medication, physiotherapy or even insoles/footwear management. For the severe or recalcitrant patients, a surgical option may be indicated.

Do see an orthopaedic surgeon that has a special interest in foot and ankle problems, and he should be able to help you solve your problem.

As Dr Sean has already provided an excellent answer, I won’t repeat what he has mentioned.

Your pain does sound like plantar fasciitis - which is based around the heel and is typically worse after rest or first thing in the morning. You could also see a Sports/MSK physician who will usually be able to provide you with a same-day ultrasound scan of the foot to help with diagnosis.

If this sounds like your pain, I would suggest a few basic exercises such as stretching the foot, the calf and the hamstrings. Often it comes on after an unusually loading or activity and can be compounded by weight etc.
