After being sick I can't eat solids, only liquids... Why?

I'm recovering from an accident in November. I know what u mean. When you get sick depending on what sickness u had u tummy becomes weak. Try to drink alot of water to streach ur tummy. I would get those vitamin drinks like insure that will replace what u can't eat. If it goes on for a month I would go see ur doctor never know u could have something medically worng w u. Try those drinks and force urself to eat it sounds bad but little bites don't hurt. Wish the best. Let me know what happens thanx
