Question: About 10 days ago i started having dizzy spells , as i do workout frequently i thought i needed some sugar but the problem fidnt stop . The next day everytime i would yawn or take a deep breath i would get light headed and dizzy . I decided to donate blood thinking my iron level was high and it was a 57 . The next morning i wake up really dizzy and out of my mind , end up going to the Er and my hemoglobin was a 20 the day after donating and my blood pressure was 180/154 . It did come down at the hospital within normal range . So they run all kinds of tests etc and all checks out fine . Just told me i needed to donate more blood and gave me a temporary blood pressure med Lisenpriol 10mg .. Following Monday i follow up with primary doctor and he runs some more test and told me to quit taking the blood pressure medicine because it was making me feel bad .. So i donate again yesterday and has me donating a few more times this week as well . My question is would this thick blood cause my blood pressure and heart rate to elevate ? And within the last few weeks i have had zero sexual drive . Last few times having sex i could not get completely hard or finish .. And the last 4-5 days i have had zero erectile function .. Could this be a result from the thick blood ? Im also on Armour thyroid ..
