Different people have different symptoms for their migraines. Some people confuse migraines for sinus headaches or problems. My symptoms are one sided headaches, near the orbit of the eye, pain that radiates like a "ram's horn" across the side of the head, base of the skull (occipital lobe region), into my neck and then shoulder. When my migraines first started they were only behind my eye. Sometimes I get a bit nauseous, most of the times not. I am not sensitive to light, but I am to smells. My guess is that the birth control pills you took that far back would not be affecting you now and you didn't take them long term. I am not a doctor though and I would suggest you talk to your doctor about your headache. They can prescribe you some medications to try to get rid of it.

My migraines are up high on the side of my head and back about 3-4 inches. I never get migraines in my eye or around my eye. The frozen gel packs work great on my migraines and I place the packs just above my neck on the back of my head (occipital area) and on the place on my head that is beating so hard with pain. Usually prescription migraine meds will make it go away.

My sinus headaches go into migraines and go across the forehead and really hurt. They will make bone around my eyes hurt. The microwaved moist heat pads feel good on my sinus headache/migraine. Nothing makes the sinus headache/migraine go away until I am on the antibiotic for a few days.

Like Sped said, a doctor can talk to you about your situation.

It does make sense to go to the doctor though I have found that hormonal issues can play a role. Spedteach talked of possible confusion but I am not sure there is a consensus on what migraine headaches are other than they are frequent and disabling.

I would do a few things:
1. Do a Google search of the medication you were on to determine side effects
2. Contact your pharmacist and ask him
3. Sometimes migraine is a combination of things like caffeine withdrawal and something you ate or the change in barametric pressure.
4. Try to think of any changes you have had. It could be something as simple as a new kind of lunchmeat (happened to me).

1. I forgot to mention that weather is various parts of the country can impact your migraines and I am one that is reactive to storms and lightning

2. Also, WATCH OUT for chocolate in holiday food. People delight in using all types of different ingredients in them and not disclosing what they use and I have to be careful because chocolate gives me a Molotov Cocktail explosive type hormone that can put me in the Hospital Emergency Room. Some people finely shave chocolate into their food and it can be hard to tell it is in there. I tell everyone that I am highly allergic to chocolate and I just received home-made cookies from a friend and half of them contain chocolate and she has been REPEATEDLY TOLD that I am highly allergic to chocolate. As I dissected what looked like a plain cookie, I found it had very tiny flecks of chocolate in it--to me it was a dangerous cookie because the chocolate wasn't obvious. ALL THE COOKIES SHE GAVE ME went in the trash and right out to the dumpster because I could trust none of them. It made me mad, but I got over it. A long time ago at a dinner where I advised the hostess well in advance that I couldn't eat anything chocolate because of allergy, I was assured it was okay and I was served a chocolate cheesecake with chocolate cookie crust for desert. I didn't eat it. DUH--like I was supposed to just ignore it. No way.

3. Wine and alcohol are also migraine triggers for me. I can refuse that served in glasses, but people are using them in sauces and in recipes and vanity sometimes doesn't allow them to state their secret ingredient. This is a problem for me. I don't go to these dinners.

4. Potpourri: I have found that people (and some work places) are putting potpourri in bathrooms. It doesn't mean much until you close and lock the door to use the room and you are stuck in there with it. Some of it just gives me a migraine.

So think about what you have been doing over the past few days. Have you been in contact with any of this? Have you been eating any homemade cookies that may have hidden ingredients? Have you been eating leftovers from a dinner and it may have hidden ingredients? Just some things to consider. Many hugs.

Many would say that pain on only one side often = migraine, especially considering the duration you're experiencing. I can't take anything, even supplements, that are indicated to help women hormonally. I've learned to stop experimenting with new products, because to mess with my hormones is to guarantee at least a week long migraine. The last thing I tried took only ONE tablet. Since we're talking about your cycle, I wouldn't discount any affect within your month long cycle being affected by what you took previously. It may be helpful to check with a dr, but everyone's so different that you may have to just figure it out for yourself and learn what to do and what to avoid. Good luck to you!
