I'm a 20 year old healthy male and for the past year every time I consume alcohol I feel a terrible pain in my sacrum/SI joint. Couple sips of beer is enough to make me very uncomfortable. I started drinking when I was 16 and had no problems about any joint pain after alcohol consumption up to now. I have been to couple of doctors and none of them have been able to diagnose what causes the problem. They always suggest that I stop drinking. I have been seeing physiotherapy and chirotherapy and they both confirmed that my joints are hypermobile but knowing that doesn't help solve my issue. I've had an X-Ray done on my back and no sign of inflammation was detected. Any suggestions on what it might be would be very appreciated.
