Your hip pain may be caused by muscle strain or stiffness from prolonged sitting during study. You may take over-the-counter paracetamol or ibuprofen for short-term pain relief if you have no allergies, stomach issues, or kidney problems. Try improving your posture, taking regular breaks, gentle stretching, and using warm compresses to ease discomfort. If your hip pain persists or worsens, or if it affects your walking, please see a doctor for proper evaluation and treatment.
