I have had fluid filled bags under eyes for the last three weeks and have tried every thing to get rid of but nothing seems to help is this a medical ?

Perhaps...: Tissue below lower lids r loosest in body, and anything that causes swelling of facial tissue will first be seen under the eyes. If you are a healthy 42 year old, the problems may be an allergy reaction to something in your environment; a state of fatigue because you haven't slept properly for a while; a recent weight gain, where you are retaining water. Try used tea bags? C doc if persists.
