I am a hypothyroid patient (used to have hyperthyroidism). Levoxyl and Synthroid of any levels cause me severe dizzy/headache spells, stomach upset, severe acne problems, high b/p, swelling. Very sensitive to synthetic medicines. No drs. seem to listen. Have to quit job. No previous health problems until diagnosed with hyperthyroidism in January 2001. Very, very frustrated. Need help/advice badly.
