Paddy McGuinness, 46, revealed in an Instagram post last year that at 44 he was diagnosed with arthritis. Arthritis is a common condition that causes joint pain and inflammation.
The arthritis charity organization Arthritis Research UK said at the time, "We thank Paddy McGuinness for speaking up and showing other young people with arthritis that they are not alone.
“People often think of arthritis as an elderly person's disease.
"But Paddy is actually one of the 11.8 million people under 65 living with musculoskeletal problems, including 2.7 million under 35."
The two most common types of arthritis are osteoarthritis and rheumatoid arthritis.
DO NOT MISS
The main symptoms of osteoarthritis are joint pain and stiffness, according to the NHS, which can hinder the movement of the affected joints and perform certain activities.
He adds: “Symptoms can come and go in episodes, which may be related to activity levels and even weather. In more severe cases, the symptoms may be continuous.
"You should consult your doctor if you have persistent symptoms of osteoarthritis so they can confirm the diagnosis and prescribe any necessary treatment."
Other symptoms you or your doctor may notice include:
- Joint sensitivity
- Increased pain and stiffness when you haven't moved your joints in a while
- Joints looking a bit bigger or more "bumpy" than usual
- A creaking or crackling sound or sensation in the joints
- Limited range of motion in joints
- Weakness and loss of muscle mass (loss of muscle mass)
Osteoarthritis can affect any joint in the body, but the most commonly affected areas are the knees, hips and small joints in the hands.
In osteoarthritis, the protective cartilage at the end of bones decomposes.
Rheumatoid Arthritis Symptoms
The main symptoms of rheumatoid arthritis are joint pain, swelling and stiffness.
The NHS advises: “It can also cause more general symptoms and inflammation in other parts of the body.
“Symptoms of rheumatoid arthritis usually develop gradually over several weeks, but some cases may progress rapidly over several days.
Symptoms vary from person to person. They may come and go, or change over time.
"You can have seizures when your condition deteriorates and your symptoms get worse."
Rheumatoid arthritis is an autoimmune disease, meaning that the immune system mistakenly attacks the cells that line the joints.
If you think you have symptoms of osteoarthritis or rheumatoid arthritis, consult your doctor.
