<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 58 year old male; 6 ft. tall, 170 lbs. History of hypertension controlled by Norvasc. 5 days ago I underwent endoscopic nasal surgery under general anesthesia. This was done at an ambulatory surgical facility and I was released home the same day. Postop problems have been minimal. No major pain so I quit taking the Norco pain med after 24 hours. My problem is that my energy level is still very depleted and I am still sleeping through the night and much of the day. Can this still be a residual effect of the anesthesia?  <response>: Hello! Thank you for asking on Chat Doctor! I carefully passed through your question and would explain that your symptoms can be related to inflammation or anemia. The effects of anesthetic Chat Doctor. So, If these problems persist, I would recommend consulting with your attending physician for a careful physical exam and some tests: - a complete blood count for anemia-blood electrolytes for possible imbalance- PCR and ESR for inflammation or infection- an arterial blood gas analysis. You should discuss with your doctor on the above issues. Hope you will find this answer helpful! Wishing all the best,
