I am a 72 year old woman. I have 40% blockage of my caratid artery on each side of my chest. I take 40 mg of Crestor every day. I also suffer from high blood pressure for which I take 50 mg of Lisinoprol. What I'm writing about is that I suffer from hypothroidism as well. For this I take .05 mg of Levoxyl for about 10 years. For the past year or so I have become exhausted particularly the past few months. I'm exhausted most of the time. I can only go out during the day due to said exhaustion. I work out in the morning 5 days a week which I've done most of my life. I pressured my PCP to increase my dosage of Levoxyl another 2.5 mg which would be 1 1/2 pills - He was a bit hesitant because of all of my ailments. Since the increase I've felt more awake, but when I work out my back hurts as well as the back of my legs. Will this subside in time. FYI - I am 5'0 inches tall and weigh about 120 lbs. Also, from your educated thought process does this make sense - the increase I mean. Will I eventually have more energy?
