May is National Arthritis Month

May is National Arthritis Month: Part 1

Whew! May is a busy month for bringing awareness to all sorts of things. I’m glad. It keeps us informed.

This is my question for this post:

How many types of arthritis are there?

According to there are more than 100 different forms of arthritis and related diseases.

Did you know this? This is news to me. We hear about a few of them in commercials all of the time, but knowing that there are more than 100 is mind blowing.

I’m going to start with the ones that we are familiar with and then work our way through the list of the ones that aren’t so familiar.

What is Arthritis?

Arthritis means inflammation in a joint. That inflammation causes redness, warmth, swelling, and pain within the joint.

Inflammatory Arthritis

Since those of us with autoimmune disorders are living with inflammation of some kind or other, here is a group of diseases characterized by inflammation of the joints and often other tissues:

Rheumatoid Arthritis

Rheumatoid arthritis, or RA, affects joints on both sides of the body, such as both hands, both wrists, or both knees. This symmetry helps to set it apart from other types of arthritis.

RA can also affect the skin, eyes, lungs, heart, blood, or nerves.

Sometimes called degenerative joint disease or “wear and tear” arthritis, osteoarthritis (OA) is the most common chronic condition of the joints. It occurs when the cartilage or cushion between joints breaks down leading to pain, stiffness and swelling.

I have this in my spine. My doctor said that when I ruptured a disc in my back, that osteoarthritis immediately started.

Psoriatic Arthritis

Psoriatic arthritis (PsA) is an autoimmune inflammatory disease. PsA affects the joints, causing arthritis; the connective tissue where tendons or ligaments attach to bones, causing enthesitis; and the skin, causing psoriasis.

Enthesitis is inflammation of the entheses, the sites where tendons or ligaments insert into the bone. It is also called enthesopathy, or any pathologic condition involving the entheses.

Infectious Arthritis

Infectious arthritis is a form of arthritis caused by an infection in the joint. It is also called septic arthritis.


Most types of infectious arthritis are caused by bacteria.


The most common symptoms of infectious arthritis are intense swelling and pain, usually in a single joint. In about half of all cases, infectious arthritis involves the knee, but hips, ankles and wrists are also commonly affected. Less commonly, infectious arthritis affects more than one joint.

Joint pain and swelling may be accompanied by other signs of infection, including fever and chills.

Last but not least on our list today is:

Juvenile Arthritis

Juvenile arthritis is an umbrella term used to describe the many autoimmune and inflammatory conditions or pediatric rheumatic diseases that can develop in children and teens.

Common types of juvenile arthritis

  • Juvenile Idiopathic Arthritis
  • Juvenile dermatomyositis.
  • Juvenile lupus
  • Juvenile scleroderma
  • Kawasaki disease
  • Fibromyalgia
  • Mixed connective tissue disease
