My email is YYYY@YYYY I just had a pain pump implanted a month ago. I had the external pain pump first with prialt and it made me sick with diahrea, nightmares, nausea and severe migraine. They informed me that it was ok to get the internal pump implanted because there are many meds they can put in it. So after the implant I went to my pain dr. and he informed me that I might have had the flu with the external pump and so he was trying prialt again. I had the same reactions only the migraine lasted 5 days and nights with no relief. Thought I would die. He took it out again. I went the other day and he now says that prialt will not cause headaches and that if my headache disappeared the day after the medicine was taken out it wasn t from the prialt because it takes 9 days for the prialt to get out of the cath. He informed me he would only put prialt in again or have the pump removed. Why is he so adament about this prialt if I can t stand it. I have been on ms contin, exalgo, fent. patches and so forth and nothing worked which is why I went to the pump. The prialt didn t take any pain away while I had it either. Now I have a mass by my cath and was also wondering if that is caused by the prialt as I read on the internet prialt site that you can get a mass at cath site. Can you tell me what could be causing the mass? I have an appt. Wed. with the surgeon and would like any info you can give me before I see him. Should I let my pain dr. put the prialt in again or what? Thanks in advance for you help....
