Hi, Welcome to Health care magic forum.
The pain started when you wake up from bed, means it is a sudden onset pain, the causes may be the
sprain, or infection. Not relieved by
steroid injection, so may not be inflammatory.
I advise you to consult an orthopedic surgeon for diagnosis and treatment . You may need to have an M.R.I, and other tests for confirmation.
He may prescribe you injections of vitamin B 1,6,and 12 for 10 consecutive days, calcium, multivitamins, antibiotic,and pain killers.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods.
Wishing for a quick and complete recovery. Thank you.
