Wife and mother of 4 living with migraines

I have been reading lots of posts and just wanted to share my story. 

I am a wife and a mother of 4 wonderful kids.  I never suffered from migranes until my last pregnancy and I have had them almost daily since.  At 1st not knowing I was pregnant I was sure I had a brain tumor, I had never felt so much pain, 2 days in a row I was in the ER, they did the cat scans, and MRI's etc and all was clear, they set me up with specialists, finally they had me go see my gyn as my cycles were still not regular from my previous pregnancy, my son was 20 months old.  This is when they told me I was 11 weeks pregnant with my 4th child!!!  So, happy day, no brain tumor, but still had terrible headaches, and now the added concern that all the drugs I had taken and the MRI and CAT scan I was going to have a baby with 2 heads or worse!  So I went through my pregnancy as drug free as I could be, getting nerve block injections into my head to stop the pain, as this would not harm the baby, just so I could get out of bed and function as a mother to my 3 children, all the time they kept telling me the headaches would stop once I had the baby.  Then my beautiful baby girl was born (with only one head, and perfect in every way) but the headaches did not go away.  So then the doctors tell me its because I am breastfeeding, so I stop nursing way sooner than I had wanted to, and here we are, my baby girl is now 3 years old, and I still have the daily headaches. I am 40 years old in good health, other than controlled asthma and daily headaches.  I have tried so many different drugs.  My current list includes topamax, soma, maxalt, and a painkiller. 

I do get shots every 3 months, that seems to help more than anything else, but I have not seen anyone else talk of them.  My doctor prescribes Botox shots ~ I get them accross my shoulders, the back of my neck and across the top of my head and forehead.  They dont stop completely but the degree of pain is reduced alot for approx 6 weeks.  Has anyone else tried this?

This looks like a great place for support ~ my husband tries, but his patience runs thin at times.  Its hard for him to understand, especially when he has so much else on his mind.
