question: My husband has been having tingling and numbness in his hands and noticed that his erections are not like "they were".  Recently he's been having headaches that go away with otc meds but come back at night and last night woke up several times feeling like he couldn't breath. Today he's been tired and has felt little irregularities in heart beat and heavyness in chest(like several years ago) we have an appt made but can't get in till fri and today is mon. What do you think?
