Thankfully I searched to see if there was any information online. Having read how many women of all ages suffer from this complaint without any obvious symptoms, I was immediately relieved to discover I wasn't alone. I made an appointment to see my female doctor yesterday who after examining me, said she couldn't find anything abnormal, and not to worry about it. I was not happy to accept her dismissal, but agreed to wait a few days to see if the swelling disappeared before making yet another appointment to see her. Thank all of you for your submissions which certainly helped me.
