thyroid and Ra

[kl42]

i have had thyroid removed due to suspicion of cancer. currently my levels came back high or hyper. I'm having a lot of joint pain stiffness and achiness, could this also be RA ? I'm on Armour thyroid replacement med now. dose was recently reduced 3 weeks ago. I'm wondering if the achiness and joint stiffness, clicking are from that or could it be something else? thanks for info.

forgot to mention. all pathology came back benign after the thyroidectomy. all margins were clear.

Dear Friend,
Since you had a thyroid cancer, chances of metastasis are high in the same.
Multiple level joint pain, in a previous history of cancer need to be properly evaluated.
I would advice you to -
1) Bone Scan,
2) Routine basic blood investigations, including ESR, CRP, CCP, ASO titre, RA factor
    which would help us to know, whether it's RA or Metastasis.

Please post me, once these tests are done.
Waiting for your reply.
Regards...
