Jugular vein symptoms and conditions

I've been on Wafarin since September of 2008 because of a massive DVT stretching from my jugular vein to my right arm. Since the initial injection of Heparin and oral consumption of Wafarin I have experienced daily migraines. They seem almost like 'pressure-headaches' pushing on the sides of my head, temples, forehead and the bridge of my nose. My thrombosis doctors have sent me for Ophthalmology tests, MRIs, and plan to send me for Neurology tests as well to discover the cause of my headaches. They've put me on codeine, Tylenol 3's, Gabapentin, Naproxen, and Co Sumatriptan because of the fact that I'm so immune to painkillers in general (For the blood clot pains themselves, I was on Hydromorphone, Morphine and Codeine). Although the Co Sumatriptan along with the Tylenol 3's give me some relief, I can't help but wonder if the cause of my daily migraines are from the Warfarin itself.
My doctors are reluctant to agree with me, saying that they plan to take me of Warfarin within the next few months, but aren't certain of exactly when.

I think some of the severe symptoms reported here are just that.. severe, and as advised on the drug information insert they can happen, and should be reported to your doctor. We are led to believe our doctors will stop the meds and try something else. If they are not willing to do that, or try to convince us it's all in our heads then... we should stop the meds ourselves and find another dr. These side effects are real, and scary. I've stopped cholesterol meds for that reason. I don't need a dr. to tell me to stop... I know my body, and how I feel and know when something isn't right.

I've been on Lisinopril for two weeks now. I was initially on the diuretic Hydrochlorothiazide, but had so much arrhythmia that I thought my heart would jump out of my throat. The dr. discontinued that after less than a week, and put me on Lisinopril. I am a bit dizzy sometimes, and do have a mild cough, but I had the cough before the meds so I can't really blame it on that. However, for all those with the problem of coughing and headaches... I read at drugs.com that you should take this medication with a full glass of water, and drink lots of water throughout the day. This tip was not in the drug handout and I thought that odd. Something so easy, and yet left out. Luckily, I drink water at my desk all day at work. This weekend while home I didn't drink water and had a horrible headache the entire time. I never connected it until I read that you should drink lots of water. Back to work today and drinking water and my headache is gone. It's worth a try, it might help. My husband is on Lisinopril/HCTZ combo, has been for at least 3-4 years with no adverse side effects.

We are all different, medication effects all of us in different ways. I hope I never experience the kinds of side effects I'm reading about here. If so, I'll be off the drug in short order. My dr. told me there are loads of other medications we can try. While there are side effects to everything we take, mild is ok but no one should put up with life altering and/or life threatening side effects like what I am reading here.
