Prolong symptoms: A second shortly after a first concussion may result iin a prolonged duration of symptoms. If this is due to a sports injury, do not participate in contact sports until you are completely symptom free. there is concern about a "second impact syndrome", when a brain is recovering from a concussion, somewhat swollen, experiencing another concussion with disasterous results.
