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.
For example, in lupus (systemic lupus erythematosus), the lining of the lungs may be inflamed, causing chest pain, and the blood vessels of the lungs may be inflamed, causing people to cough up blood (hemoptysis). In systemic sclerosis (scleroderma), lung tissue becomes scarred and people have trouble breathing.
