Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for severe breathing difficulty, collapse, or signs of a serious allergic reaction.
Contact your surgical team promptly if you have increasing redness, warmth, swelling, wound drainage, fever, worsening pain, or numbness that is new or clearly worse.
Also call if the wound opens or the dressing becomes soaked with blood.
Seek urgent assessment if your fingers become pale, blue, cold, or very swollen, or if a dressing feels dangerously tight and symptoms do not improve after following the team's instructions.
These are not routine recovery symptoms.
For routine questions about scar tenderness, returning to work, exercises, or slow improvement in numbness, contact the team during normal hours or discuss them at follow-up.
Every sign above is quoted from the sofidex article on Carpal tunnel release. If you are not sure, err upward — it is always reasonable to be checked.
