The effects of scar tissue shrinking and maturing result in adhesions which pull on nerves and other structures. This often result in brief shooting or electrical pains with motion, particularly when the patient stretches their hand out to reach an item at arm's length. Sudden shooting or electrical shock pains may also occur spontaneously while the patient is doing nothing. Both of these are normal occurrences and improve with time.
Shrinking and swelling associated with scar maturation results in the feeling of a lump at the surgical site.
