All I can stress is make sure its in your medical records. For 5 years my husband went under the radar and we were lucky he had a really good doctor that was detailed. We also provided MFR's from his coworkers, and his migraine log.
My husband is like yourself seated or laying position is all that helps him keep his sanity. Do the medications help you at all? He has tried everything we have researched but nothing helps, prevents, or treats the pain. We met someone who received 10% for his migraines but his main condition was back problems. He had migraines 6-7 times a month, but it matters how bad they are. Yours sound similar to my husbands so make sure you stress what you go through when you meet with your doctor, their notes are a huge factor.
Along with my husbands migraines he has other things that further the impact of the migraines. He gets severe neck and back pain to the point that he cannot move. Picture keeping a book on your head and sitting or standing and walking he is very slow and has very limited movement. His claims on cervicalgia and lumbago were rated a 0%. He has had to see the Chiropractor for 4 years now and they didn't see anything significant to rate it above a 0% so they can be brutal.
I have never heard of anyone getting 50% for Migraines.
People told me not to even consider it.
I have what they call Right Side Cluster Migraine Headaches....basically it start by hurting to see through my right eye...blurred spots...then the right side of my face and head is just done. it is a strange pain in the eye socket. I have had them for two years first one came on like a stroke... Been treated by a neurologist for the last year at an Amry hospital. My VA C&P exam put down 4 to 8 a month and needs oxygen and seated or laying at 45 deg for optimal breathing and take pain and nauseau medicines. I do not know what the reasoning is behind 30% or 50% etc.
my doctor knows i was tired of trying meds...been through about 4 preventitive and 3 or 4 treatment. Then i was diagnosed with cancer (Malignant Melanoma) on my right cheek and of course i want to know if it has been causing my eye and head problems. they cut it out but still don't know. I now have a few things with the headaches and cancer. Here is kind of what i'm thinking
DoD Unfitting
Migraines 30% (I would love 50% but i cant get my hopes up...I will appeal anything less than 30%)
Malignant Melanoma 30%
Trigeminal Neuralgia with Cranial Dystonia (could be 30% could be 10%) basically numb face right side with a hell of a tic
VA
OSA 50%
Migraines 30%
Melanoma 30%
Trigeminal Neuralgia 30 or 10
left shoulder cartledge injury 10%
left knee meniscus tear 10%
Horner's Syndrome 0%
Bladder Void Dysfunction 0%
Chronic Rhinitis 0%
Hypertension 0%
So I'm planning in my head for Dod 50% VA 90%
