The patient did not experience tingling, numbness, or pain during the injection, which clinically rules out intraneural injection, and there were no signs of nerve damage intraoperatively and a full neurologic function had been regained, so it is believed that the cause of acute CTS in this case was injection into the nerve sheath. C) observing how the cluster bends light from galaxies located behind it Sodium gives up its valence shell electron (becoming a cation) to drop back to a stable valence shell, and chlorine gains one electron (becoming an anion) to fill its valence shell and become stable.
