My daughter recently had her Mirena removed and immediately her blood pressure became dangerously high. Drs are baffled and normal meds for high blood pressure aren't working. She's afraid of stroking out while she sleeps. She cannot go back on hormone therapy because there is a tiny blood clot in her carotid artery. Anyone else have this problem: formation of blood clots in arteries or higher blood pressure? Has this happened with other birth control methods?
