Hi Becky,
Sorry you are still in so much pain.
I am on Enbrel,(also on prednisone, azulfidine, 20mgs of MTX per week,
8 pills, and ultram for pain )and I have lots of problems with muscles
in my calves (in the back, like those leg cramps that wake you up
during the night?), my forearms, shoulders, etc...

I was also diagnosed with fibromyalgia about a year after the first
arthritis problems started (I have ankylosing spondylitis). My RD seems
to attribute a lot of my muscular problems to my fibro.  I also have
lots of problems with my achilles tendons-plantar's
fasciiitis-inflammation where the tendon inserts into the bone. I also
experience pretty bad back spasms at times.

For me, it did take about 3 months to get the full effects of the
Enbrel.
I doubt this helped you at all, (sorry!) but these have been my
experiences,
Char

Thanks to everyone for the replies, yes I was diagnosed with first
connective tissue then they changed it to FM then about 5 years later they
threw in the RA diagnosis.  It is very frustrating. To top it off tonight
when I took out the enbrel the needle had all been bent I didn't notice that
when I got the box, guess I should look at those carefully when I pick them
up. Had to really jam it since some of hte point was gone, hope it was okay
to use it.
Thanks again for the replies it helps to know others are going thru a lot of
the same.
Becky
