Brief Answer: anesthetic being the cause is very rare Detailed Answer: Hi, I went through the query and understood your concern. If your symptoms are recent onset, then the chance of anesthetic drug causing the problem is very rare. As by this time the anesthetic drug would have been completely removed from the body. Anesthesia can cause these symptoms after 4 weeks if you have any problem in the vital organ functions. If no problem then anesthetic drug being the cause is very unlikely. The other cause common causes for illness post surgery is decreased activities or any infection if your Hb % is normal. So to overcome the problem, do regular exercises, plenty of fluids with good nutritious diet. Check for complete hemogram once to rule out any infection or anemia.
