So (ignoring unicode for the moment) you can send a message of 35 * 153 = 5355 characters via the Clickatell API. If you are sending unicode characters (which the OP is not) the character count for a single message is 70, reduced by 7 characters for each segment in concatenated message or 63 * 35 = 2205 unicode characters.
Lung-related causes. Many lung disorders can cause chest pain, including: 1  Pulmonary embolism. 2  This cause of chest pain occurs when a blood clot becomes lodged in a lung (pulmonary) artery, blocking blood flow to lung tissue. 3  Pleurisy.
Pneumothorax occurs when air enters the space around your lungs, or the pleural space. Air can find its way into the pleural space when thereâs an open injury in your chest wall or a tear or rupture in your lung, disrupting the pressure that keeps your lungs inflated. Itâs known as a tension pneumothorax when the lung wall is affected, or an open pneumothorax when the chest wall is affected. Causes of ruptured or injured chest or lung walls can include lung disease, injury from a sport, or even changes in air pressure that you experience when scuba diving or mountain climbing. Sometimes, the cause of pneumothorax is unknown.
