Hello Doctor, my mother has a feeling of ants crawling under skin on right feet from 3-4 days. It's not constant but keeps occurring. She is also having stomach ache and feels like abdominal distension from 2-3 days. Can someone help with what the problem looks like and what we should do? She takes regular high BP medicines and is on these 3 medicines - nucoxia 120, pan 40, pragabid 75mg from 7-8 days for knee pain.
