<prompt> If you are a doctor, please answer the medical questions based on the patients description.Lately I ve noticed I have been retaining water I m 53 going through pre-metapause. Thus morning I woke up to my right ankle very very swollen slowly as the day went on I noticed it was my entire leg. It seems as if I lay down and raise it the swelling goes down a little. Should I go to the ER?  <response>: Hi my dear, I have gone through your medical history carefully and understood your concerns. Retaining water edema at your age 53 years old while going through pre-menopause is to get further evaluated by physician. Immediate tests are highly recommended to understand why you are having edema: - liverkidney function test-cardiac check up- Doppler ultrasound of the blood vessels including lymphatic system-lymphatic studies MRI, ct-scan to rule out lymphedemas the swelling is progressing and noticed on your entire leg, throughout the day, I highly recommend going to ER as immediate evaluation and specific treatment might be needed. Wish fast recovery.
