It may be normal to have some swelling in the hands and especially in the ankles, legs and feet in the 38th week of pregnancy. However, if there is sudden swelling in the hands and face, it may be a symptom of preeclampsia and you should see a specialist as soon as possible.
Other symptoms of preeclampsia include sudden weight gain, headache and vision changes, nausea and vomiting, abdominal pain and decreased urine production.
