Achy joints

I've been on NDT since the beginning of November 2016 & doing really well.

However, for the past 3 days I've had an achy feeling in my knuckles & finger joints - this went away with ibuprofen. Today I'm starting to feel a few twinges in my elbows & knees too.

I started taking 200ug of selenium on Thursday & not sure if this could be causing the issue or if this is just coincidence. I haven't taken any today but I'm still feeling the ache.

Has anybody experienced this?

Your ferritin and vitD are okay so I think the likeliest reason you are experiencing joint pain is that you are over medicated.


Thanks Clutter - I know you said that to me at the time. I'll reduce meds & see how I go. Thanks for your quick response.


How bizarre as I too have been getting very achey in those places too over the past month...even my bottom cheeks ache as I walk (shhh.....keep that bit between us 🐴). Initially I put it down to my gardening work but I sense it's more than that.

Interested to see what others might suggest.


I've had achy joints recently, but not on NDT. GP said auto-immune diseases just move around the body attacking different parts, so one week it may be problems with joints, another week fatigue may be the most noticeable symptom.

I've got Graves' disease

And those were pretty much the first symptoms I had ... there were many others of course

But those were the ones that made me know I was becoming ill

I thot it was arthritis ...

but it certainly was Graves !

Best of luck

I take 100 gms thyroxine per day and have been on this med for at least 15 years but I am suddenly getting aching lower legs every night and I am going to check with my doctor if my thyroxine could have changed so will also get a new blood test taken as I am losing sleep with the aching legs
