I've had ringing in my ears constantly for a couple of years now. It has increased in volume. I don't really think it is connected to the Tec. I had to go for my annual MRI's yesterday and needed to do a repeat liver functions bloodwork so I figured I would do it just before the MRI's. I knew I shouldn't take Tylenol #3 for the migraine so I had to put in the call to my neuro. I just started the 240mg dose today of the Tec. I am feeling a little better, physically. I am concerned about my white count, we saw a big drop in my white count with just 5 injections of Copaxone. Time will tell.
