Nicole,
I got deblitating headaches post-op (after sutures were taken out and swelling started) that felt like my head was going to explode. I didn't get them near my incision either. At first, I treated with Tylenol 3 (with codein) but after the doc saw me and thought it mights be CSF built up, he put me on a diruretic (diomox?). The way I described it to my doctor when I saw him was that it felt like my eye was going to pop out! After being on the diruretic, the swelling has gone WAY down (at first, within an hour of taking off the "wrap" it would come back and now I had it off for 7 hours before it started coming down) and the headaches are non-existent. I also take Allegra D for my allergies. Between the two, the headaches are gone...*knocks on wood* Of course, my doctor took me off the pain meds while I'm on the current med.
Are you running any fever along with it? Swelling? This may seem like an odd question, but what kind of headache? Is it external or internal?
Have you contacted your doctor's office about it yet? If not, I suggest going through him first.
I hope you get relief soon!
