Hi,
Welcome to ehealthforum,
It is difficult to comment on the sharp pain that you describe without examining you. Possibility of nervous or vascular origin cannot be ruled out. If the symptoms are persistent, you should consider visiting your doctor/gynecologist for further evaluation and assistance. Treatment as indicated (based on examination and investigations results) would be started to help you control the symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
