Hi, Welcome to Health care magic forum.
As you describe, it appears to be the
viral fever, after 5 days, during coughing, your collar bone started hurting, and it is still continuing.
It appears to the fever related
arthritis, i advise you to consult an orthopedic surgeon.
You may need to have M.R.I and other tests for diagnosis.
I usually prescribe to my patient with such symptoms neurotrofic injections for 10 consecutive days, and then periodically. Supplements of calcium, vitamin D, and pain killers.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods.
Wishing for a quick and complete recovery. Thank you.
