Causes of gastric. Overcome from this.

Dear doctor, Due to series of family functions couldn't have food properly. Because of this in the end of the may month had severe bloating. For this doctor prescribed Pan 40 and Rantac msp syrup for ten days. Before finishing the course I had mouth ulcers as well as teeth tenderness, gum pain, ear pain headache and shoulder stiffness. Now I don't have mouth ulcer but have teeth tenderness, ear pain, gum pain as well shoulder stiffness. I have visited dentist about teeth problem. They said everything is fine. Please suggest does gastric cause above problem. Even stress and sleepless night cause above problem. I am bit worried and not able to concentrate on kids. Your answer makes me really relax and suggest what should I do to overcome from this. Thank you for all.
