<s>[INST] I just received a phone call from my drs nurse saying my labs taken yesterday show that my creatatine (sp) is high and borderline calcium. She scheduled me to see him at his first available appointment, which is next Tuesday. So, I m left wondering if this could cause my extreme fatigue, bone pain, problems mixing up my nouns, increased forgetfulness, and heat intolerance? [/INST] Hello, Welcome to Chat Doctor. I read carefully your query and I understand your concern. I see your description; you say that you have high creatinine blood test and a borderline level of blood calcium. The creatinine high level shows us that you have problem with your kidney function and this is related with the borderline blood calcium and your symptoms of fatigue and bone pains. You should go to nephrologist to determine your stage of your failure kidney function or your kidney disease that cause these problems and to follow up with medications and other blood tests. 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. Kind regards, Chat Doctor. Maria BANK </s>
