It may be calcaneal spur dear ..Or your plantar fascia is extremely shortened so it's creating devastating pain while walking. .I wish u go to a physio rather wasting your time to any orthopaedist ..
Just approach to a sports physio with expertise in dry needling with kinesio taping application..Some issues are also there at tendoacvhilies and gastrocnemius-soleus .
Thats will be easily managed
Next Steps
in either case u don't need to worry as your muscles only will protect you while walking. ..
Health Tips
in general u can go with contrast bath .
hot water immersion for 5 mnts followed by ice water immersion for 3 mints. repeat twice that is for 16 mnts in one sessions and do it again before sleep
