I was involved in a severe car accident totaling my car and flipping over another vehicle. I briefly lost consciousness and walked away with no visible marks. Later the same night I experienced soreness on my right side from under my right shoulder blade, down my lower back into my glut and around to my hip. I went to the er and they said I had muscle sprains/strains and spasms. I also explained I ve had extreme thirst and occasional vomiting and nausea. Please advise me what to do next.
