After getting gallstones, three or four days after minimally invasive surgery, red lumps appeared on

Cholelithiasis patients need to rest in bed after minimally invasive surgery. If they stay in bed for a long time, the friction stimulation of the waist will increase, which may lead to skin redness or edema. If secondary infection occurs, red pimples may also occur. Red pimples may also occur due to skin allergy. Do not keep a posture for a long time when lying in bed. The mattress should be cleaned and exposed frequently.
