Your doctor can provide specific advice based on your medical history and the severity of your symptoms. Always be honest and thorough when describing your experience. Keeping a record of your symptoms, including the time they occurred, can be helpful for your doctor.
Remember, seeking help is not a sign of weakness; it’s a responsible approach to your health. Your well-being is paramount.
