Hi,
Welcome to ehealthforum,
It is difficult to comment on the cause for the pain that you describe without examining you. Avoid any movements/activities that aggravate the pain. Visit your doctor at the earliest for further thorough evaluation and assistance. Get started on treatment for symptom control as indicated by examination findings and investigation results. Be in regular monitoring and follow-up with your treating doctor and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet.
Take care.
