Hi, I had gone through your reports and question and understand your concerns. Please don t worry and have peace at your mind as there is really nothing to worry...! even if the statement Left kidney contains a hypoechoic area lower pole hilum favor artifact from medulla less likely 1.5cm parapelvic cyst is fact rather than artifact, it is going to stay as it is possibly throughout your life! regarding Sometimes having problems urinating and have also had slightly low potassium of 3.0 and sugar cravings... I would say that the problem could be in pancreas/insulin and prostate; therefore if you are male please revert back to me with PSA /prostate status! regarding I am starting to feel sick again. Nausea, muscle pain and weakness, constant headaches sharp chest pain at times extreme fatigue... I must suggest EEG, ECG, Chest X-ray, Upper G.I endoscopy if needed and still all are normal please consult a psychiatrist as all could just be symptoms of depression.....! Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
