It is normal to feel a little chest tightness, chest pain, and slight pain in the axillary incision after surgery. Do not touch the water on both sides of the wound until the stitches are removed, and if you accidentally get wet, you should immediately replace the disinfected gauze to keep the wound dry. The stitches should be removed at the local health center or hospital outpatient clinic on the 7th-9th day after surgery. You can take a bath 2 days after the stitches are removed.
