I just took Novahistex dh and my blood pressure went high and I feel like vomiting. wondering if that caused the feeling.I have been ill with flu symptoms with either bronchitis or pnemonia. what should I do. I also, have had my thyroid removed so I have to take the medications. Just read side effects of the novahistex but wondered after taking this, I felt tingling, cold clammy, sweating & felt like fainting, then felt like I was going to throw up but haven t yet. Is there another reason for those symptoms like onset of a heart attack as I think there could be other reasons for me feeling this way?
