Eighteen male patients with primary syphilis were randomly assigned to one of the following treatment schedules: ceftriaxone (3 g in a single intramuscular [im] injection), ceftriaxone (2 g im daily for two days), ceftriaxone (2 g im daily for five days), and benzathine penicillin (2.4 X 10(6) units in a single im injection).
Motion Sickness - One of the most common causes of dizziness accompanied by nausea and vomiting is motion sickness, which is a normal reaction to head motion. Symptoms usually start with paleness of the skin, followed by yawning, sweating and restlessness.
Tension headaches are not associated with nausea or vomiting, and do not have symptoms like flashing lights, blind spots, or numbness or weakness of the arms or legs which precede the headache. These symptoms can help distinguish tension headaches from other types of headaches (for example, migraine headaches).
