Swollen feet can happen for a number of reasons.
If they are swollen all the time, this may be from a heart of kidney problem.
If you get swelling of the feet a few days before a period - it will be due to hormonal changes and referred to as premenstrual tension (PMT) sometimes referred to as premenstrual syndrome (PMS)
If you have been doing a lot that you are not used to, a strain on the muscles, ligaments and any injuries can also causing swelling.
Other illnesses can also cause swelling of the feet and legs.
Make sure that you still drink plenty of fluids. Drinking less will not help to reduce the swelling. It is still important that you drink fluids so as not to get dehydrated.
When at home, take your shoes off and elevate your legs so that they are raised and not on the floor.
Make an appointment to see your doctor to rule out any serious medical conditions.
Best wishes.
Pain should not be the determining factor in whether or not to see a physician. A lot depends on the age of the patient, but abnormal venous preload can represent a life-threatening condition, as can kidney failure, and there will not necessarily be pain.
Cutting to the chase, unless it is a one-time thing, chronic swollen feet mandate an in-person evaluation.
Normally feet swell if your on them a lot. walking, standing, running. etc. Its not really something to worrk about. Unless its causing a lot of pain and if it is then see a doctor. Sometimes when i was younger i still had growth plates in my feet because i was still growing and my feet would swell and hurt and the doctor just said its because you are growing and on them so much. i played a lot of sports.
The swelling is from fluid retention, and there are many possible reasons, some serious, and others not-so-serious. . When this happens it's a good idea to see a physician for an in-person evaluation.
