Rheumatoid arthritis
Rheumatoid arthritis is an autoimmune condition that causes the immune system to attack the joint lining. This condition is quite common among women than men and typically strikes between the ages of 40-60 but can occur at any age.
The exact cause of the disease could not be determined but genetics might play a role in making an individual susceptible to it. Rheumatoid arthritis often triggers systemic symptoms such as fatigue and fever but most of the damage is focused on the joints particularly on the feet and hands. This condition destroys the bone and cartilage in the joints and loosens up the tendons that hold the bones together. An individual with rheumatoid arthritis has a risk for developing rheumatoid nodules which indicates that aggressive treatment is required.
Dermatomyositis
This is a muscular condition that causes chronic inflammation and weakness of the muscles. In most cases, a skin rash is the indicative sign of this condition which manifests before the muscle symptoms. The rash is red or purple and most often appears on the eyelids, knuckles, toes or knees, but can occur on the face, back, chest, neck or upper shoulders. Exposure to light can often aggravate the muscle symptoms.
Gout
Gout is a form of arthritis triggered by excess uric acid in the bloodstream. An individual has excess uric acid before any symptoms manifest, eventually forming into crystals in the joints and can cause an acute attack.
The acute attacks of gout can affect the joints of the big toe, feet, hands, wrists, knees or ankles. These attacks are intensely painful along with swollen, red-colored bumps on the joints. The tophi are nodule-like masses of monosodium urate crystals caused by years of chronic gout. Take note that these bumps are likely to manifest on the finger joints, hand, wrist, elbow or Achilles tendon.
Granuloma annulare
Granuloma annulare is a condition that triggers red-colored bumps or ring-shaped lesions on the skin, particularly on the feet, hands, knees or elbows. Aside from reddish in color, the bumps can be purple, skin-colored or pearly white that can oftentimes itch. Most of these bumps vanish after a few months.
Lichen planus
Lichen planus is an inflammatory disease that triggers a rash in purplish-red, flattened bumps that are often itchy. The rash manifests on the skin, including the fingers but particularly the wrists and ankles. Many consider this as an autoimmune disease but not contagious.
