Hello, From your description you are most probably suffering from gastrooesophageal reflux diseases (GERD) which could be treatment effectively provided you quit alcohol for a while until the GIT lesion (ulcer or inflammation) that is present is completely healed. (quitting alcohol all together will be the best thing to do). You will need to see a gastroenterologist who will do an endoscopy to confirm GERD and see the extend of the affection. Major complications that can arise from GERD/ peptic ulcer diseases is digestive hemorrhage to hemorrhagic shock to death. Treatment with protein pump inhibitors (PPI) like omeprazole, h2 inhibitors like ranidine, cimetidine etc and antacids has proven to be very effective provided you have a lot of discipline when it comes to alcohol and smoking. Oesophageal tumor or gastric tumor are other conditions that could cause your heartburn. Your left hand soreness might be unrelated to the heartburn/acid reflux and so will need to be examined by a doctor ( could be an inflammation, or passive soft tissue pain/neuralgia). Hope this helps
