My ANA was negative. Is it possible to still have RA, Lupus, or Fibromyalgia?Lyrica (pregabalin) is NOT helping the leg/arm/hand/foot pain. CRP is 6.5.

In brief: Yes due to FALSE NEG

Every test in the world has a FALSE NEGATIVE rate which tells what percentage of the time a test comes out negative but really it should say positive.
It is rare for someone to have RA, LUPUS, or FM and have a positive ANA.... on the order of much less than 1%. will be FALSE NEGATIVE.

The tests are not falsely negative, they are just negative. The ANA is negative in 3-5% of SLE patients and 80% of RA patients.

In brief: Fibromyalgia ?

Leg arm hand and foot pain is neuropathy until proven otherwise.
Fibromyalgia ?!? Joint pain is another matter (still not fibromyalgia) See a neurologist.
