<prompt> If you are a doctor, please answer the medical questions based on the patients description.I HAVE BEEN TAKING MY MOTHERS MOTRIN, ONLY 2 IN THE LAST 2 DAYS I FEEL LIKE I WANT TO VOMIT BUT NOTHING COMES OUT ONLY MUCAS..THEN I TOOK 2 ADVIL 4 HOURS AGO, I HAVE SEVERE BACK PAIN SO THAT IS WHY I AM TAKING THIS... IT FEELS LIKE MORNING SICKNESS...I AM 52 YEARS OLD...I AM AT WORK BUT WILL BE LEAVING SOON..I DONT FEEL GOOD.  <response>: Hi, Thanks for the query. I understand your query. It seems you have taken the Motrin on an empty stomach you are already a hyper acidity patient. So the pills had given you the nauseating feeling. Advil. Again a pain medicine added to the problem. You should - - Consume a pill of performmetoclopramide over the counter with a bit of water. no more pills without a doctors advise please - Take a glass of cold milk sip by sip after half hour of the pill. - Take tab Sanitizing 150 mg twice a day for following 3 days avoid spicy food, tea, coffee, fast. if there is no relief there is increase in the symptoms . Visit ER for injectables. Your backache needs an orthopedic consultation, investigations as per need specific treatment not any painkiller to postpone it in future. Thanks.
