Are there tests for psoriatic arthritis?

[Caroline]

I asked if I might have it, and they said I did based on the fact I have had Achilles tendinitis, plantar fasciitis, and I have carpal tunnel as well though I can't remember if that counts.. Anyway, they said yes, I did have it just based on those things, no swollen joints as yet.
I asked if they could test to confirm and they said no, it was a 'clinical diagnosis' and I could take it as confirmed.

Ooo, but that is interesting. I did a lot of running before I got the PsA, and indeed my achilles also gave me trouble, that might have been an early warning !!

I remembered we had this if it helps: Achilles tendon ultrasonography may detect early features of psoriatic arthropathy

quite interesting. That maybe is why this problems also disappeared by the use of DMF.
