I have experienced chronic migraines for many years. They have taken much joy and opportunity from me and my children.
In my opinion I don't think it's the Paxil..rather...other dynamics are at play here, possibly.
Hormone levels, ect.
Best thing is to ask your Doctor.
When I get a migraine...I lay down with a bag of ice and do rythmic breathing. Have you tried anything like this with any success?
Keep us posted!!
