Hyperemia is just a term for increased blood flow to the area, often due to inflammation. This, combined with the vomiting and pain, could suggest issues like gastritis, ulcers, or even gallbladder problems. I recommend you schedule an appointment with a gastroenterologist for a thorough evaluation. In the meantime, try eating smaller, more frequent meals and avoiding spicy or acidic foods. Stay hydrated and consider using a heating pad for the discomfort. 

Kidney problems can sometimes cause stomach discomfort due to their close proximity. Common causes could be kidney stones affecting the urinary tract or kidney infections. Stomach problems like gastritis or ulcers may also lead to similar symptoms. To address this, it's best to see a gastroenterologist for proper evaluation. They might recommend tests like blood work or imaging scans. In the meantime, staying hydrated and eating a balanced diet can help. 

Chronic gas, bloating, pain, and constipation can be caused by various factors like dietary habits, stress, or even underlying conditions like irritable bowel syndrome. In fact, it's great that you've already tried medications, probiotics, and tests to get to the bottom of this. Next steps could involve keeping a food diary to track any triggers, staying hydrated, and incorporating more fiber in your diet. I recommend checking back with your gastroenterologist to discuss these ongoing symptoms and explore further treatment options.
