Hi Deb,
Sorry to hear about your continuing headaches!
Have you tried the drug "Fioricet" or "Butalbital/ APAP / Caffeine TB" ? This drug is designed specifically to stop headaches. It was given to me because I had bad reactions wirh narcotics, especiially, Morphine. In fact, to this day if I take even an Acetaminophen with Codiene (tylenol #3) I get a ripping headache - and I am not prone to headaches. Interestingly enough, when I went in the hospital for an upper endoscopy, I was given Demeral and a tranquilizer, which also rendered me with the same type of headache that I would get from the other narcotics. Have you considered the possibility that you may be experiencing an adverse reaction to the meds they have you on?
Also, I think you should contact the doctors that performed the surgery on you at House. They will take an active and concerned role in getting to the bottom of this. Tell them about my experience if you have to. Just get this taken care of ASAP so you won't be plagued
with those headaches any longer and you can move on to living a quality and fun life again.
Do a Google search on the drug I told you about for more info.
Take care, Paul
