Headaches that worsen under bp medication

[kristiexr7]

I am a 34yo white female. I was diagnosed with high blood pressure after the birth of my second child, however did now have hbp during my pregnancies. I gained quite a bit of weight with my second child. When my 2nd child was about a year old I began having "headaches". My doctor assumed this was related to my bp and put me on fluid pills (dyazide)  which infact, did regulate my bp. However the headaches were probably 80 % worse than they were with the hbp. The headaches are not normal headaches. They occur with physical exertion, sometimes, but almost everytime I cough. The pain comes up the back of my neck and then "washes" over my entire head with a throbbing pulsation I would say is 3 times as bad as contractions. It lasts from 3 seconds to 3 minutes, then either completely goes away or is followed by a normal, numb headache. Lying down helps it to ease within a minute or two most of the time. The first doctor I saw ordered a ct scan with and without. The results were ok.
I quit taking the dyazide simply because it was too unbearable. The headaches were so bad I could not do my normal housework or take care of my kids while I am on the medicine and my bp is normal.
I could tell that my bp was still high and I went to another doctor who prescribed me Benicar for the bp. The headaches became too much to bear again. The closest definition I have found is "primary cough headache", however I am not in the norm of risk factor group.
I have been healthy most of my like aside from asthma when I was younger, and I smoke a pack of cigarrettes a day.
I have trouble understanding how a problem can worsen when my bp is under control and I feel 300% better when it is high.  135/100. 140/100.

I am not sure your headache, which sounds like a tension headache, is related to your blood pressure. Hypertension can cause headaches, and it would be very unlikely that two completely different drugs caused you the same symptom. I would seek urgent neurological assistance in this diagnosis, because it may have some very dangerous causes ( such as intra cranial AVMs) which are the most common cause of non accidental death in your age group and are not sen by CT scan of the brain. You need a dedicated MRI/MRA to document these. Once these are ruled out, more organic causes of headaches can be considered

My wife has similar problems kristiexr7. Started Dyazide two weeks ago. Next day she has pain in her neck that radiated up into the back of her head.  It was a constant pain, not throbbing, not associated with exertion, but nonetheless it was a new type of h/a that she never had before (she is in her mid 40's).  Stopped taking Dyazide a few days ago, headache eased the next day, and was gone by the 2nd day without meds.  She started taking Benicar HCT a over a year ago.  From the start she felt rotten every day. Said she felt like she had to "make my legs" walk - always felt tired. Also had soreness in between her shoulder blades. Dr. said it was muscle soreness from exercise. She stopped taking Benicar HCT a month ago and felt great the following day.  All the symptoms she had for a year were gone within 24 hrs after stopping the medication. Was hoping that Dyazide would be better but we are back to square one again. She is at the point where she say "no meds."
