The pathophysiology is not yet well understood. Leukocytoclastic vasculitis is proposed to be the underlying cause resulting in reactive lymphedema. [2] Prolonged standing with full knee extension and minimal movement for a prolonged period of time is postulated to induce a temporary failure in pumping the venous and lymphatic systems in the calf region leading to acute gravity-dependent ...
If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces. The capillaries may break, leaving small blood marks under the skin. The veins themselves can become swollen, painful and distorted – a condition known as varicose veins. [17]
Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis , injury to the ligaments or meniscus , or fluid collecting in the bursa , a condition known as prepatellar bursitis .

The synovial sac of the knee joint can, under certain circumstances, produce a posterior bulge, into the popliteal space, the space behind the knee. When this bulge becomes large enough, it becomes palpable and cystic. Most Baker's cysts maintain this direct communication with the synovial cavity of the knee, but sometimes, the new cyst pinches ...
Doxycycline can cause gastrointestinal upset. [70] [71] Oral doxycycline can cause pill esophagitis, particularly when it is swallowed without adequate fluid, or by persons with difficulty swallowing or impaired mobility. [72] Doxycycline is less likely than other antibiotic drugs to cause Clostridioides difficile colitis. [73]
Flesh-eating bacteria cause woman, 33, to go into sepsis. Diagnosed with necrotizing fasciitis, she reveals symptoms, including a swollen knee.
The legs and face are the most common sites involved, although cellulitis can occur on any part of the body. [1] The leg is typically affected following a break in the skin. [1] Other risk factors include obesity, leg swelling, and old age. [1] For facial infections, a break in the skin beforehand is not usually the case. [1]
