You can if you want but you should expiate for the oath that you break by feeding 10 poor people with the average food that you eat or clothe 10 poor people or free a slave. If this is not possible then fast for 3 days.

Few years later i sweared and made a promise to Allah that i won’t eat certain things for the rest of my life if my mother is cured from the illness..She is alright now Alhamdulillah n now m craving for those foods..I was asking whether i can eat those foods again?..What if i pray istikahara?..
