Fatigued muscles from RA or Lyme's?

[Guest guest]

Hi all,

So far the obvious symptoms of my daughters RA-like condition have been pain and

inflammation of the knuckles on her right hand and in the corresponding foot

knuckles/toes.

She's very athletic -- loves to work out and play soccer.

Usually, she does her sit-ups on a decline (head lower than feet, making them

much

harder) and does several sets of 30 sit-ups.

The last couple days, however, she can't even do three sit-ups on a flat

surface. She

doesn't have any pain in her abdominal muscles, but she just can't do them.

It's as though

the muscles won't work.

My wife and I are concerned, to say the least, as we are not aware of this

specific symptom

being part of RA.

Does this sound familiar to anyone? In the symptom descriptions I've found thus

far I _do_

see fatigue listed. Can it be to this degree while limited to just the few

joints?

As always, thank you all for any and all help and advice.

God bless

Lee
