Hi, it looks like you almost certainly had a kidney issue when you had your symptoms of bleeding with burning urination. This picture is usually due to a stone or infection, but the only way to know if you have indeed passed a stone or not is to get some minimum tests done like an ultrasound of your kidneys and bladder area along with an X-ray of the same area with a urine examination for any evidence of infection. On the other hand your hives are not likely to be due to the kidney problem, and if you have upper abdominal discomfort that gets worse with alcohol, you might have sever gastritis and try avoiding anything that exacerbates it like alcohol, coffee, spicy food. you can try using antacids and medications like Ranitidine but if things get worse, you might need an endoscopy.
