I was diagnosed with PMR about 4 years ago and was down to 4mg of cortisone with very little pain. I have had ongoing problems with my Achillies tendons (and have posted on here quite a few times) They have now got a lot worse. I went to my Rheumy about a month ago and he suspects either RA or PsA. Is it possible to have either one of those in addition to PMR or could the intitial diagnosis of PMR have been wrong?
He has put me on Methotrexate in addition to increasing my dose of cortisone.
Initially my tendons were a lot better but now I'm back to square one. I know that Achillies tendon problems are not typical of PMR unless you have taken quinolones. I don't even know if mine are arthritis related either, I find the vagueness of the cause and diagnosis very confusing.
