I've been experiencing strange symptoms for the last week. Left underarm pain, neck tightness-as if my head is too heavy for my neck, feel faint and lightheaded, nauseous at times, fatigued, and a feeling of blah.. I've had EKGs performed, and bloodwork done-all normal. Also, BP of 166/106 before taking lisinoprol. Just not sure what could be wrong with me.
