When can we start eating normal food?

I removed my upper wisdom tooth last Thursday. It's been a week and I still feel tightness and stiffness in the first and second molars. So I couldn't chew even on the opposite side.the bite feels so hard while closing mouth.the upper molars feel so hard and tight. Couldn't bite at all. While biting, they gives sharp pain in the lower jaw under ear and inside the ear. Is this normal?I was having only soft foods till yesterday like mashed vegetables, puddings. I didn't have any stiches after extraction. Dentist said I didn't need any stitches since it's upper wisdom tooth. I am not sure if stitches are not required. Only today I ate some semi solid foods like dal kichdi. It was so mushy, so I didn't puree it. I ate it along with mustard seeds, jeera in it. I am just worried if those get stuck in the extraction site while swallowing. I did salt water rinse after eating.Can I eat food with those? Do I need to avoid mustard seeds, jeera ? When can I start eating normal food? when it heal?
