Thank you for asking at Ehealth forum!
I read your question and I understand your concern.
The only solution is replacement of hip joint if you are experiencing severe pain during walking. I would suggest you to take oral steriod like prednisone for 2 weeks and look for the response. Otherwise surgery would be the ultimate option.
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
