<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello! I am a 25 year old woman with asthma and a few allergies house dust and some types of pollen, but otherwise in good order. However, about two years ago I have started to feel a sharp, oscillating pain that lasts for 15-20 minutes and comes on after a few sips of alcohol. It happens under no other circumstances, but it doesnt happen every time I have a drink. The temperature or type of drink seems to have no effect. I thought it might have something to do with my liver, but I recently had my liver tested during a general check-up, and it was fine. I dont binge drink, nor do I get drunk. However, I have a very high tolerance of alcohol so when I do go out drinking which is perhaps twice or three times a month I may drink on average more than others. What should I look into?  <response>: Hi.
