sudden and
severe headache, confusion, problems with vision, speech, or balance;
chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling;
sudden cough, wheezing, rapid breathing, coughing up blood;
pain, swelling, warmth, or redness in one or both legs;
