I just started taking Diovan (one dose) after taking another bloo...

I POSTED A FEW DAYS AGO ABOUT ALL OF MY SIDE EFFECTS, BUT MY DOCTOR MENTIONED TO ME SINCE THEN ,THAT "NOVARTIS", WHO MAKES DIOVAN MAY HAVE CHANGED THE FORMULA, WHICH IS PERFECTLY LEGAL, HE SAID. THEY DO THIS WHEN THE PATENT IS ABOUT TO EXPIRE SO THAT COMPANIES WHO MANUFACTURE GENERICS CANNOT DO SO.THEY ARE ABLE TO EXTEND THEIR PATENT FOR A CERTAIN LENGTH OF TIME TO AVOID COMPETITION. I WAS DUMBFOUNDED!
SEVERAL OF THE POSTINGS HERE HAVE MENTIONED BEING ON DIOVAN FOR YEARS, AND THEN LATER ENDING UP WITH SEVERE SIDE EFFECTS.
I, PERSONALLY, DID NOT EXPERIENCE THE PAIN IN MY FEET & LEGS & THE MUSCLE WEAKNESS UNTIL A FEW MONTHS AGO. I AM ACTUALLY HOBBLING AROUND NOW. BUT I DIDN'T HAVE THIS SIDE EFFECT THE FIRST 2 YEARS WHILE I WAS ON IT.
I SEARCHED THE FDA WEBSITE FOR FORMULATION CHANGES, BUT DID NOT SEE ANY. I AM GOING TO CALL NOVARTIS THIS WEEK & ASK THEM. DOES ANYONE THINK THEY WILL TELL ME THE TRUTH?
ONE OTHER THING MY DOCTOR MENTIONED WAS THAT POSSIBLY THEY ARE IMPORTING CHEAPER INGREDIENTS FROM ANOTHER COUNTRY. I HAVE HAD A LOT TO THINK ABOUT THIS WEEKEND, BUT FOR ABSOLUTE SURETY, I AM GETTING OFF OF THIS DANGEROUS DRUG !!!
