What causes left flank pain and low grade fever?
Also have skught sore throat and belching excessively
It is hard for me to come up with a diagnosis that can explain all your symptoms, and I recommend scheduling an appointment with your primary care physician. Certainly left flank pain combined with fever makes me worry about a urinary tract infection that is traveled up into the kidney. The kidney is located in the flank and whenever the infection travels up towards that area can cause pain. A urinary tract infection that travels up to the kidney is also known as pyelonephritis. This is the condition that I think you should be evaluated for first. The sore throat and belching are not really symptoms that go along with a urinary infection. However, I do think that acid reflux is a possible cause of both of these symptoms. Belching is a common symptom with acid reflux as it is a sore throat. Another possibility is that you have a viral infection that is causing the sore throat and the belching is just something that is happening to you right now and is unrelated to it. I would suggest that you schedule an appointment with your primary care physician. The two of you can discuss the symptoms and come up with a diagnostic plan. The first step is probably to do a simple urinalysis to see if you have a urinary tract infection. If you do, then an ultrasound of your flank maybe needed to make sure that you don't have an abscess. If you still have a sore throat, then your doctor might want to do a swap of your throat to make sure you don't have strep.
