No, the carbon dioxide, a gas, goes out with breathing. We breathe a lot per minute so the gas moves very quickly out after surgery. The pain issue would depend on where the pain is. The Body implies the ache is everywhere. There really really rarely can be muscle breakdown after surgery due to a very rare interaction if the medications were right and your genetics were wrong (it is a rare interaction of genetic predisposition and some anaesthesia medicines). You don t have it; if the muscle break down from RHABDOMYALYSIS, the muscle goes into the urine and the urine is muscle colored. You would have noticed. Then, movement is changed by surgery and people invariably lay wrong with it. You did have this. It goes away generally in 1-3 days. If longer, it can in general be helped by over the counter aspirin like drugs, but anyone after surgery needs to have clearance that these drugs are safe to take. Increasing movement, warm showers, some physical therapy are all beneficial.
