Thanks for posting your query.
Pain in arch of foot and walking disability
suggest Plantar Fasciitis
, which is inflammation of plantar fascia (thin ligament that connects your heel to the front of your foot).
It can be caused by strain or trauma.You are at a greater risk for developing plantar fasciitis if you are overweight
or obese.Women who are pregnant often experience bouts of plantar fasciitis.Simply wearing shoes with soft soles and poor arch support
can also result in plantar fasciitis.
apply ice for 15 to 20 minutes three or four times a day to reduce swelling.
Using arch supports in your shoes and doing stretching exercises may also help to relieve pain.
(Motrin or Advil) and naproxen (Aleve), are often used to reduce inflammation in the ligament.
If symptoms dose not resolve contact your doctor for further management.
Hope it helps!
