I Have Had A Meningeonoma Left Frontal Brain Tumor For

I have had a meningeonoma left frontal brain tumor for some years, causes extreme pressure vice migraines I've tried many medications,but Fiornal#3 works. A few months ago I was told it had aspirin in it but Fiorcet #3 does not it has acetaminophen so I had my Dr. change. Since on I do not get any relief as I did with Fiornal#3. Is this my imagination or could their be a difference? Thank You, Marie
