The equivalent injury to a ligament is a sprain. [1] Generally, the muscle or tendon overstretches and partially tears, under more physical stress than it can withstand, often from a sudden increase in duration, intensity, or frequency of an activity. Strains most commonly occur in the foot, leg, or back.
This causes inflammation, and in turn pain due to the accumulation of histamines, prostaglandins, and potassium. [7] [9] An earlier theory posited that DOMS is connected to the build-up of lactic acid in the blood, which was thought to continue being produced following exercise. This build-up of lactic acid was thought to be a toxic metabolic ...
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
Knowing the symptoms that can be experienced with a sprain is important in determining that the injury is not really a break in the bone. When a sprain occurs, hematoma occurs within the tissue that surrounds the joint, causing a bruise. White blood cells responsible for inflammation migrate to the area, and blood flow increases as well. [2]
Inversion Ankle Sprain: landing on an uneven surface sprains the ankle. Swelling, localized pain, difficulty bearing weight, and limping are signs of an inversion ankle sprain. [23] Eversion Ankle Sprain: injury related to the ankle turning outward or rotating externally. A typical symptom of eversion ankle sprain is excruciating pain that ...
Inflammaging is thought to be caused by a loss of control over systemic inflammation resulting in chronic overstimulation of the innate immune system. Inflammaging is a significant risk factor in mortality and morbidity in aged individuals. [2] [3] [4] Inflammation is essential to protect against viral and bacterial infection, as well as ...
An injury to a ligament is called a sprain. The American Academy of Orthopedic Surgeons defines ACL injury in terms of severity and classifies them as Grade 1, 2, or 3 sprains. [1] Grade 1 sprains occur when the ligament is stretched slightly but the stability of the knee joint is not affected.
A shin splint, also known as medial tibial stress syndrome, is pain along the inside edge of the shinbone due to inflammation of tissue in the area. [1] Generally this is between the middle of the lower leg and the ankle. [2] The pain may be dull or sharp, and is generally brought on by high-impact exercise that overloads the tibia. [1]
