'I've been in a lot of pain': Adam Thomas shares diagnosis of chronic condition affecting Strictly Come Dancing training

Adam Thomas has been diagnosed with rheumatoid arthritis.

The former 'Emmerdale' star - who announced earlier this week he'll be taking part in the new series of 'Strictly Come Dancing' - has been "in a lot of pain" for several months and after undergoing extensive testing, he has been told he has the chronic condition, which causes pain, swelling and stiffness in the joints.

Sharing a photo of himself with wife Caroline and their two children, he wrote on Instagram: "Well it’s my birthday tomorrow and I turn 35!!

"How did that happen, does this mean I should stop acting like a kid now haha. As much as I act like a kid, my body is telling another story…

"I’ve been in a lot of pain since January, it started with my knees and then traveled to my wrists, fingers and now ankles and toes.

"I never knew what was happening and finally after several blood tests and back and forth to doctors and hospitals, I’ve been diagnosed with rheumatoid Arthritis!

"I thought that was something people, later on in there life get… but that’s not the case, clearly!(sic)"

Adam is thankful he is able to get his condition "under control" but admitted it has been "hard" not being able to train for 'Strictly' properly because of the pain he's in.

He continued: "It’s been a tough old year but … Finally I’m on the right plan now! Finally getting it under control. For now!

"But some days are better than others and am not going to lie, it’s been hard not being able to train properly, it’s has had a huge knock on effect for me personally, but not only that for my family too!!

"And I just want to say thank you to @carolinethomas23 and the kids for going on this journey with me, as I know it’s been challenging and frustrating at times but hopefully we’re on the right path now! (sic)"

The actor is "still learning" about his condition and signed up for 'Strictly' in a bid to be active again.

He wrote: "The reason I signed up to Strictly is because I just want to be able to move again, get fit and do it, all with a smile on my face!

"It really couldn’t have come at a better time I’m a firm believer of everything happening for a reason, and I know the journey I’ve been on was meant to happen, to never take small things in life for granted! …Like going for a run, playing with my kids and just being able to walk with no pain!

"I know it’s going to be tough and I’ve definitely got my work cut out but am up for the challenge and can not wait to get on that dance floor!!(sic)"
