Dart tablets contain paracetamol, aspirin, and caffeine. While they can help with mild pain, they may not be effective for specific types of headaches, such as migraines or sinus-related pain, which often cause one-sided pain around the eye. Because this has lasted for four to five days and worsens at night and morning, I highly recommend consulting a healthcare professional. They can help identify the exact cause and prescribe targeted, effective treatments. In the meantime, try to rest in a quiet, dark room, stay well-hydrated, and apply a warm or cool compress to your forehead.
