"I am 26 and otherwise perfectly healthy. I quit Seasonale after two months when I discovered my blood pressure had become very high (164/112). I had also been experiencing neck pain, a pressured feeling that seemed to be in my veins, which would alternate from one side of my neck to the other, since the second or third week of taking this pill. I was sent for many tests and found that one of my kidneys was mildly swollen (hydronephrosis). It took six weeks for my blood pressure to normalize, it would go down and then back up again. I was very concerned, anxious and depressed. I took hypertension medication for about two weeks as well, and was eventually able to lower my dosage and then stop it altogether."
