It : It is abnormal to have the stabbing pain in your left side especially, and you need to have a medical evaluation. You need to have evaluation for this and for endocrine (hormonal) causes of your symptoms. Please see your doctor as your symptoms are concerning and you need a medical evaluation. If your pain worsens, if you have vomiting or fever, then you need emergency evaluation.
