Headaches!

I hate headaches! I know everyone does, but I REALLY hate them. I have suffered from them since I was 5 years old. The last 7 or so days I have been waking up every night and suffering through them for 2 hours during the night. I had hoped they were not the clusters again. Ya, I suffer with clusters too; on top of sinus, tension, migraines, and some aggravated from the arthritis in my neck. I finally decided they were not (yeah!) clusters when it did not respond to a DHE45 shot. So I ended up at the Doc-in-the-Box with my self diagnosis and she agreed. After looking at my red throat and red and swollen sinuses she gave the shot of steroids I requested and a prescription for antibiotics, which I did not request. I went to have the prescription filled at Wal-mart, not my normal place, and remember the DR is not my usual either. Neither place had all the list of all the stuff I am allergic to. The pharmacist did ask about allergies, but I wasn't feeling the greatest and couldn't remember them all. When I went to pay, not only was it almost $100.00 it was one I was allergic to. I called my regular DR and updated the list; it was then switched to a $4.00 one. NOW my question...If they could prescribe $4.00 drugs WHY are DRs still prescribing expensive ones???? The Drs warning about not sleeping and being hungry from the steroid shot was true, but at least I like to eat and was not awake most of last night from pain!! Sinus headaches suck! If you are suffering from one defiantly go and get a shot so it will go away. It shrinks the membrane in the sinuses and relieves the swelling in your head. I will turn in my DR licence now. Have a good one. Off to try to get my car air conditioner fixed.
