Got second opinion from other doc but still confused.../sinus/alergie?

i just contacted second doc about my problem and he confirmed what first one said.... BUT....
I was diagnosed to have sinus infection/alergie 3 month ago.
Symptomps: weekness,headache in the front and lower back of the head.

I was taking sudafed and drops until 10 days ago.All problems were gone after one week....

Immidiately after i stoped sudafed (10 days ago) i experienced dull headache again in lower back of my head (right side).

Doc said its normal cuz sinuses go all way around head and also nerves in the back of head are connected with that.
But i dont have any pain/headache in the front anymore!! Only in the back!!

All my friends who have alergies or sinus problems never experienced headache in the back,spec for so long time (10 days).

Anyone here with same problem?
I started using sudafed again so we will see how it goes .....

well, every person has different genes

a drug may cue someone's disease, it can cause another person very sick

headache is especially hard to cue, unlike a broken bone or a bleeding stomach, there is really not a machine that can detect headache, and many reasons can cause headache, brain chemical imblanace can cause it, too, and we certainly can't open up someone's brain and see what is causing it

if sudafed works, keep taking it. it is a vasoconstrictor, it makes the blood vessels diameter smaller.

If you have a sinus infection you need antibiotics. Many doctors do not prescribe enough antibiotics for a sinus infection. Sinus infections are mean and take at least 2 weeks worth of antibiotics if not 3 weeks. I get headaches, toothaches, etc. w/ sinus infection.

I actually have the same problem. Often a "sinus" headache starts in the back of my head and only does the front of my head start to hurt if my sinuses get really bad. I thought I was crazy/had a brain tumor/hurt my neck until my doctor told me about the referred pain (since the nerves run along the same pathways.) I've found keeping my seasonal allergies under control are about the only thing that helps. Unfortunately I still have headaches pretty frequently. I use a sinus rinse bottle that helps (I can't use Sudafed because it dries me out so bad I can't stand it, also makes me feel weird-kind of spacey.)
Good luck! Hope the Sudafed works again. If not, then back to the doctor!

First, are you using sudafed or sudafed D. Always pick sinus meds with a D for decongestant. When I can't get prescription meds, I always take Muccinex D (one pill 2x a day) and nasal spray to clean out sinus cavities. If you don't use a decongestant, you never actually get rid of the infection.
