Thank you for your question, and I am sorry to hear about these disturbing symptoms that are clearly having a significant impact on your life. In order to provide an answer, I would need more information. I would need to review your entire medical history and also perform a thorough physical exam. In addition, you may require other testing, including blood work and imaging studies. Only after collecting this information will it be possible to determine if you are suffering from a serious illness
or something more benign. Therefore, I strongly encourage you to schedule an appointment with a primary care doctor
Pain in the kidney area could be due to an infection in the urinary tract. It can often be treated by oral antibiotics. However, if the infection has traveled to the kidney itself, you may require hospitalization and intravenous antibiotics. Fatigue and coldness may be indicative of thyroid dysfunction, and this is typically ruled out by basic blood work. Chest pain has many potential causes. This could be due to gastroesophageal reflux disease, coronary artery disease, costochondritis, pneumonia
, or a cardiac arrhythmia. It is not possible to determine the cause from the information provided, and I strongly encourage you to see a primary care doctor.
