I have had hydrocephalus since age 10. I have had 5 operations at ages 10,11,15,16 and 18. At the age of 18 I started experimenting with marijuana and found that this is a cure for me. I am 36 and have not had an operation since. I have never quit because there is no more pain. I really don't get headaches either. If you are desperate for a cure than look no further. Any medical marijuana doctor will not turn you away for this illness. I have recieved 6 medical marijuana evaluations from 3 differnt doctors and had no problem. Infact they didn't even need any paperwork because the proof is in my head and neck. So if you live in a state that approves medical marijuana then go get a doctors reccommenation. Then you can go to dispensaries and be pain free like me.
