Recovery guide Pain management
Recovery doesn’t have to hurt
There is a persistent idea that pain after heart surgery is a test of character. It is not. Uncontrolled pain keeps you still and shallow-breathing, and both of those cause complications.

Where the pain actually comes from
It is easy to assume the pain is the incision. Mostly it is not. The sharp pain when you cough, laugh, sit up or roll over is the two halves of the divided sternum moving against each other and pulling on everything attached to them.
That distinction matters, because it points to the fix. Skin pain needs time. Mechanical pain responds to stopping the movement.
Why bracing works
This is the reason every cardiac ward hands out a cushion to hug. Bracing the chest before a cough takes the movement out of it.
The limitation is obvious: a cushion works only while you are holding it, and you are not holding it at 3am or in the car. A fitted support vest applies that same light front-to-back stabilisation continuously, which is why patients describe the difference in terms of sleeping and travelling rather than pain scores. It is also the approach with randomised trial evidence behind it.
Take the pain relief properly
Prescribed pain relief works best taken on schedule rather than once pain has already escalated. Its purpose is functional: to let you walk, breathe deeply, cough and sleep. Judged that way, taking it is the responsible choice, not the weak one.
If you are worried about the medication itself — constipation, grogginess, dependence — raise it with your team. There are usually adjustments. Stopping quietly and enduring is the option with the real downside.
When pain is telling you something
Pain that is escalating rather than settling, pain with a click or movement in the breastbone, pain with fever or wound changes, or new chest pain different in character from your incision pain — all of these are reasons to ring your surgical team rather than to increase the paracetamol. In an emergency call 000.
Questions patients ask
+How long does chest pain last after heart surgery?
Incision and sternal pain usually eases steadily over the first weeks as the bone knits, with occasional twinges and nerve sensations along the scar for months. Pain that escalates rather than settles should be reported.
+Why does it hurt so much when I cough?
Because a cough drives the two halves of the divided breastbone against each other. Bracing the chest first — with a cushion, your arms, or a fitted support vest — substantially reduces it.
+Should I try to avoid taking pain medication?
No. Pain relief after cardiac surgery is functional: it lets you walk, breathe deeply and sleep, all of which prevent complications. If side effects are the problem, ask your team to adjust it rather than stopping.
