Hi,
Welcome to ehealthforum,
The symptoms that you describe could be suggestive of possibility of vaginal infection, internal injury etc. If the symptoms have been persistent (for more than 48 hours) and if they are getting worse, you should consider visiting your doctor/gynecologist for further evaluation to look for the underlying cause. Get started on treatment as indicated. If infective cause is detected, get your partner also treated simultaneously to prevent chances of re-infection. Drink plenty of water. Avoid unprotected sexual contact.
Take care.
