When you're losing your mind, your sanity, have no health insurance and already tried a doctor once with no results and are left with no money.. the only thing you can do is the thing that takes the agonizing migraines away.. take some medicine. Then a year goes by and you still can't find a job and running out of money and losing even more of your mind... People commit suicides over migraines like this.. I went with the better option of taking more medicine.
What am I suppose to do after racking up over 20k in medical bills and still have no results? (that's what would have happened because I spent my entire childhood and over 100k from lawsuit winnings on medical costs.. They would have told me the same thing as those previous doctors I was assuming)
I can't slap my dick on the counter and expect them to accept payment.
yes, but all medicine also says to consult a doctor when said you've been using said medicine for X amount of time with no relief from the symptoms they are treating.
That's when doctors can help look at the pain and say "well, this medicine isn't doing it, it might be a different pain symptom resulting from a problem that requires treatment with different medication". Or in your case, with enough trial and error (believe it or not, this is modern medicine still - trial and error while more conclusive evidence is sought after, which takes a lot of time), they would have discovered the medicine itself was causing headaches.
Now the real question is: you were using Excedrin daily, correct? For 2 years? What kind of dosage/frequency, assuming daily but how many times each day, how much each time?
The next step you should do, is get some tests done to see if that extreme amount of chemicals over the two year period has caused any permanent damage, specifically to the liver and/or stomach.
