I have had depression for 25 years and had most of the differennt anti-depressants. However, in the last 2 years have been experiencing a really bad pressure headache ie worse when bending the head, coughing, sneezing etc. Doc tried different tabs, lately lithium, but all drugs do the same thing. May not now be able to take anything, and have to live with this depression. Has anyone else had the same thing? Does anyone know what causes it and if there is anything I can take that won't bring on this headache?
