Chronic Sinus Migraine suffer for over 12 years. Botox last resort.

In response to those who have tried Botox injections.
I have also tried Botox injections; I just had my second set on October 15th. I have been suffering chronic/daily migraines for over 12 years and have tried all the medications and injections with no relief. I had 5 sinus surgeries in a 6 year period of time and only started getting migraines after the 5th surgery. My CAT Scans and MRI come up clear every time. I suffer fatigue, confusion, memory problems, moodiness/irritability, auras, light sensitivity and lack of energy and have lost at least 2 jobs because of how the chronic pain affects me. I was unemployed for over 3 years and just started a new full-time job in August (I tried to find a part-time on) I am not sure how much more I can take of working full-time. I have become very unsociable and angry. I have been to Sinus Specialists, Neurologists and University of Penn for the sinus problems with no success. I have tried alternate therapies with no success. Unfortunately for me the Botox was my (latest) Neurologists last ditch effort.
After the first set of Botox injections I began seeing double and had to go to an eye specialist for the double vision, not yet realizing it was from the Botox. It took about 2 months before I got everything straightened out with my vision but I still was unusually tired with eye fatigue. I could no longer do my one main hobby in life "reading". My vision won't allow it for more than 20 minutes at a time. So we kinda get the vision thing straightened out and what happens, it's time for the second round of 35 Botox injections. I received those on Oct 15, almost immediately my vision went double again, I broke out in a horrible itchy rash and I still suffer from daily migraines from a level 5 up on an everyday 24/7 basis. I will not be going back for more injections they are causing more harm than good. Here it is almost 3 weeks after the injections I am still itching like crazy and my vision is off. It's a struggle to get through every minute of every day. I have fallen behind in life again - that is what life I had. I have only one joy in life and that is my dog Brie, and unfortunately she is getting up there in life and I don't know how much longer she has 1-2 years maybe??? She also suffers due to my migraines as I cannot walk her everyday anymore; I barely make it through work. Every day after work I come home and nap to try to get some kind of relief - but I never get that rested feeling. I have trouble sleeping and take medication which compounds my fatigue. I am a walking zombie.
I also suffer from lower back problems which also limits my movements. I am at wits end, I don’t know where to go. I am 44 and can only see chronic pain for the rest of my life. I’ve already used up all my sick time at work and will have to either take vacation days or unpaid days off when I am deeply suffering. I snap at people when I’m suffering, I try to hide, stay away from everyone including family. They suffer too. I have lost all belief in anything, no hope or dreams left in life.
I question how much longer I can keep up a full-time job, I was denied disability. It’s only me. I live with my elderly mother and that is the only reason I have a home to live in.
So I have been in and out of various specialists for the last 12 years with no obvious success. I’m ready to throw in the towel. Fortunately friends and family have not yet given up on me. I contacted John Hopkins University Hospital in Baltimore, MD today as recommended by a friend. I have to get back to them with my history and believe me it is a book! I really don’t have any expectations from going there.
I just don’t want to do this anymore but I will not end it, it is not in me to do so. Any suggestions/ideas would be helpful.

I have tried every migraine medication they gave me with no luck. This includes BUT/APAP/CAF, Imitrex (pill & shot), Maxalt (Rizatriptan), Prop Naps w/APAP, Zomig, Hydrocodone/APAP, Relpax
Inderall LA (Allergic) and that is only since I started tracking them.
My diagnosis is chronic migraines and chronic sinusitis. None of the medications they tried helped, even a prescription pain medication does not even help. I know my triggers, sensitivity to light, eye pain, nausea, confusion, and irritability. I have a somewhat sedentary lifestyle and that is mostly because of my chronic pain. I do all the yard work and house maintenance at home. I have trouble reading or watching tv, my main hobby is reading. I work and do a lot of walking at work and have recently lost 40 pds. And I do believe a Neurologist is a headache specialist, let me know otherwise. I feel like every time I go to a doctor's they try things at first and then I start hearing "I don't know what else to do for you". My neurologist finally suggested the Botox injections and they somewhat help but the side effects (double vision and eye pain and rashes make it not worth it), and it doesn't take the pain away but does dull it a bit so I can function at work (for the most part). I have just recently am trying magnesium but it's been about 3 weeks and I have not seen a difference. Remember we are talking about over a decade of dealing with this and going to specialist after specialist. Prescribing drug after drug with no relief. Unfortunately after each attempt at getting help with no results I stop for a while, give up the doctors have not given me any hope for even getting some kind of relief. Then a year or so later I try again cause I can't take it anymore. I was out of work for over 3 years because I lost my previous job from missing so much work due to the migraines.

I agree with much of what has already been said. I would def say to look closely at the diet. Gluten sensitivity and/ or food allergies can also cause or contribute to much of what you are dealing with. I would highly recommend using the Paleo diet as it will eliminate most all possible allergens.

Actually, I personally eat paleo and really enjoy it!  Yeah, it took a lil while to get used to it but I have found a ton of good recipes online so I actually really enjoy the diet now.  Of course, health-wise I am much better for it!
