I'm A 55 Year Old Female Who Came Down With

I'm a 55 year old female who came down with an apparent stomach virus a week ago. I had vomiting on and off for two days. Day three I was able to start holding down liquid and solid mild food. I'm able to eat a normal diet now six days later, but now I feel like I was punched in the stomach, and also my lower back is hurting. (I do have a bulging disk, but I haven't done anything to aggravate it). Eating helps some. I feel somewhat fatigued since this started. just wondering if I'm just still recovering, or if I should see my doctor.
