I spent some time working in the garage - the temperature was in the 80s.  I had a fan for air circulation. Since noon I have had an upper stomach ache and have vomited 7 times so far.  I have tried to keep some water and small amount of food down - no luck. What can I do?
Hello and welcome to Ask A Doctor Service. I reviewed your question and here is my answer. What had you taken in food? It may be a food poisoning. Or it can be a pancreatitis. If you have pain in stomach going back or which is relieved by leaning forward then it is moat likely pancreatitis for which you need to see a doctor.  If it is not that severe pain, and you are just vomiting, then its most likely food poisoning, for which you need to keep your HY Chat Doctor.  You may also need to do some test in order to rule out other causes of vomiting. Hope I answered your query, feel free to ask if u need further assistance or want to give more details. Thanks. Regards.
