Multiple Joint pains, negative to all the blood test except ANA

Hi everyone,

I had suffered from chronic left arch pain.
I had been smoking for 5 years, about a half pack per day.

I stopped smoking but my pain became worse.
I felt pain in my left arch, left knee, achilles tendon (Bilateral)
Then my pain spread to knuckles of fingers (Bilateral), wrist

I had blood tests, and everything(C-Reactive Protein, HLA-B27, CK, C4 & C3 Complement, DSDNA, RA, Anti CCP, Scl-70) was negative and normal except ANA positive 1 : 160, homogeneous.

Also my doctor ordered X-ray for my knee, but normal radiograph was obtained.
She even said that there is no sign of inflammation or swelling.

I had red, dry eyes, and was seen by an ophthalmologist, but he did not see any inflmmation.

I have seen three rheumatologists and both of them concluded that I do not have lupus nor any other autoimmune disease.
Moreover, all of them examined the body parts but they did not figure out inflammation.

I also have been suffering from weird left rib pain, but X-ray was normal too.

However, my joint pain is improved but not gone totally, and since yesterday, it became worse again.
My left knee pain is chronic and I feel random joint pain (i.e. joint pain migrates - fingers - wrist - hip - elbow etc)
I was not given any medication other than Naproxen.

What should I do?
Should I request MRI for my knee and arch?

Is it possible to have RA even all the markers are negative? (Including RA, Anti CCP negative)

I am a 23 year old male, Asian, no family history of autoimmune disease.

Thank you BadDay,

I am from South Korea, but now I live in Los Angeles, California USA.

None of the doctors told me about Lyme.
I had simple blood test on 12/6 and more complicated one on 12/11.
dsDNA was weak positive from 12/6 result but negative from 12/11 result.

CRP, ESR, and other markers for inflammation was normal.

I saw my doctor 2 days ago and asked about whether I need redo the blood test, but she said no need to do so at this moment, may be after 3 months if pain still remains or worsens.

The most difficult part of visiting Rheumatologist's office over here is making a reservation. To see some popular doctors, 1 months minimum waiting time is normal.
Anyway, thank you for your answer.

Thank you Girlie,

I heard that the first symptom of lyme is its typical rash.
I never had such rashes before, though I had some other types of rashes caused by holter monitor pads.
Also doesn't it accompany fever? I went to doctors' offices nearly 10 times or more since last November but never had fever..

However I believe it is important to clear the possibility of lyme.. if you can, please let me know some of the tests. Or maybe I can request the test during my next visit.
