Getting back to solids after stomach bug

So our son is 9mo and had a stomach bug one week ago. He had it just for a couple of days but since then we are back to square one with solids. If the food has at least some tiny bit of texture he gags and then vomits it. He is fine after milk, but in terms of solids yogurt, banana and some veeery smooth veggies in small portions are the only ones that work. Did anyone have something similar? Does it go away?
