This condition can persist for more than 48 hours and may be accompanied by nausea and profuse perspiration.

Pain and cramping can spread rapidly to the arms, legs, chest, back and abdomen. Swelling is often experienced in the extremities. In severe cases, victims may experience delirium.

However, some symptoms may continue for much longer after recovery.A victim’s age and health condition are important factors in severity of symptoms. Small children and elderly patients are more at risk, as well as those with compromised immune systems and heart conditions.
