Can Levothyroxine cause fluctuation in blood pressure?

Hello doctor,

I am a 56-year-old female. I am 30 lbs overweight. I had a total thyroidectomy two years ago and I take levothyroxine 150 mg daily. Other than that I am healthy, active, and jog three miles three times a week. For the past two weeks, I have been off. I have felt severe headaches, dizziness, and blurred vision. I went to urgent care twice this week and ER two nights ago. ER gave me something for migraines, EKG and CT came back fine and blood pressure was 155/90 mm/Hg. After IV and medication, I returned home better. Yesterday my headache and all symptoms returned strong. My blood pressure (I bought a machine) was 160/98 mm/Hg for a few hours so I finally went back to urgent care blood pressure was still 167/95 mm/Hg so MD prescribed blood pressure meds lisinopril so I took that at 10 pm and by midnight my pressure finally down to 137/ 80 mm/Hg. It has remained at 137/80 mm/Hg and of course, I still have a slight headache because my normal bp has always been 120/80 mm/Hg. I am scared to take my levothyroxine this morning because it makes my heart beat faster, and makes me anxious. So I am scared my BP will jump up again. Should I skip it for today or possibly take only half of my levothyroxine? I still have no clue what caused my BP to jump so high for a full week now but do not want to end up in the ER later today.
