Arthritis is often used to refer to any disorder that affects the joints. Rheumatic diseases usually affect joints, tendons, ligaments, bones, and muscles.
Rheumatoid arthritis, or RA, is an autoimmune and inflammatory disease, which means that your immune system attacks healthy cells in your body by mistake, causing inflammation (painful swelling) in the affected parts of the body. RA mainly attacks the joints, usually many joints at once.
Multiple sclerosis, rheumatoid arthritis, and polymyalgia rheumatica are three types of autoimmune disorders that affect the joints or nerves. Autoimmune disorders occur when the body's own immune system mistakenly starts attacking healthy tissue.
If you have rheumatoid arthritis, your immune system mistakenly sends antibodies to the lining of your joints, where they attack the tissue surrounding the joint. This causes the thin layer of cells (synovium) covering your joints to become sore and inflamed, releasing chemicals that damage nearby: bones.
The most common viruses causing arthritis and/or arthralgias are parvovirus, the alphaviruses, hepatitis B, hepatitis C, Epstein-Barr virus (EBV), and tropical viruses, such as Zika and chikungunya (CHIKV).
Acute pain in multiple joints is most often due to inflammation, gout, or the beginning or flare up of a chronic joint disorder. Chronic pain in multiple joints is usually due to osteoarthritis or an inflammatory disorder (such as rheumatoid arthritis) or, in children, juvenile idiopathic arthritis.
Arthritis is the swelling and tenderness of one or more joints. The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age.
The most common form of arthritis is osteoarthritis. Other forms include gout, rheumatoid arthritis, and lupus. Symptoms of arthritis are pain, aching, stiffness, and swelling in or around the joints. Rheumatoid arthritis and lupus can affect multiple organs and cause widespread symptoms.
Lupus can also cause inflammation in the joints, which doctors call “inflammatory arthritis.” It can make your joints hurt and feel stiff, tender, warm, and swollen. Lupus arthritis most often affects joints that are farther from the middle of your body, like your fingers, wrists, elbows, knees, ankles, and toes.
Neurogenic arthropathy results from an underlying disorder that affects the nerves, such as diabetes and stroke. People develop neurogenic arthropathy because they cannot feel injuries that damage their joints. Typical symptoms include stiffness, fluid, and pain in the joints.
Musculoskeletal pain
Back, neck and joint pain can be indirectly caused by MS, particularly for people who have problems walking or moving around that puts pressure on their lower back or hips.
Some of the main blood tests used include: erythrocyte sedimentation rate (ESR) – which can help assess levels of inflammation in the body. C-reactive protein (CRP) – another test that can help measure inflammation levels.
A vitamin D deficiency can affect both physical and mental health, but many people have low levels of vitamin D without realizing. The physical symptoms of a deficiency may include muscle pain in the joints, including rheumatoid arthritis (RA) pain, which often occurs in the knees, legs, and hips.
Rheumatoid arthritis, lupus, juvenile idiopathic arthritis, and Sjögren's syndrome can have systemic involvement, as well as spondylarthritis (which includes psoriatic arthritis), ankylosing spondylitis, IBD-associated arthritis, and reactive arthritis.
Autoimmune diseases can affect many types of tissues and nearly any organ in your body. They may cause a variety of symptoms including pain, tiredness (fatigue), rashes, nausea, headaches, dizziness and more. Specific symptoms depend on the exact disease.
Symptoms are usually severe and include fever, redness, and swelling at the joint and intense pain that worsens with movement. In infants, symptoms may include a fever, the inability to move the limb with the infected joint, and crying when the infected joint is moved.
The most common type of bacteria that causes septic arthritis is called Staphylococcus aureus. It is also known as S. aureus.
The typical symptoms of COVID-19 range from those resembling the flu or a bad cold to ones that are much more severe. However, there are less frequent symptoms you probably wouldn't expect that follow some people both during the illness and long after recovery. One of those is muscle and joint pain from COVID-19.
MS can appear at any age but most commonly manifests between the ages of 20 and 40. It affects women two to three times as often as men. Almost one million people in the United States have MS, making it one of the most common causes of neurological disability among young adults in North America.
