"i have pseudotumor cerebri which means false tumor. it is like i have a large tumor in my head but i do not have the mass. i have everything else, high fluid pressure on the eyes, severe headaches. they are worst the migraines, which i have everyday. the patch relives that a lot. i have had 9 surgeries in the past 8 years. i have three shunts, 2 in my head and one on my spine. the one on my spine makes my lower back hurt. i have been dealing with this for 8 years since 2002. in 2009 i found out i also have arnold chiari malformation which means your brain is to big for your head and it falls down in your neck. fentanyl 75mgs every 3 days has been a gift. the only thing i do not like is 48 hours after i change my patch i get in pain again."
