The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...

Cadaveric spasm is seen in cases of drowning victims when grass, weeds, roots or other materials are clutched, and provides evidence of life at the time of entry into the water. Cadaveric spasm often crystallizes the last activity one did before death and is therefore significant in forensic investigations, e.g. holding onto a knife tightly. [4]
At times, DVT can cause symptoms in both arms or both legs, as with bilateral DVT. [25] Rarely, a clot in the inferior vena cava can cause both legs to swell. [26] Superficial vein thrombosis, also known as superficial thrombophlebitis, is the formation of a blood clot (thrombus) in a vein close to the skin.
With proper surgical care, acute limb ischaemia is a highly treatable condition; however, delayed treatment (beyond 6 to 12 hours) can result in permanent disability, amputation, and/or death. Early detection and steps towards fixing the problem with limb-sparing techniques can salvage the limb.
Erythromelalgia in hands of a Scandinavian male, 52, after holding a book). The most prominent symptoms of erythromelalgia are episodes of erythema, swelling, a painful deep-aching of the soft tissue (usually either radiating or shooting) and tenderness, along with a painful burning sensation primarily in the extremities.

Most commonly, the legs or arms are affected. [1] Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. [1] Other symptoms depend on the underlying cause. [2] Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections ...
Onset of symptoms may be after just a few minutes, but usually occurs after at least 20 minutes of free hanging. Typical symptoms are pallor, sweating, shortness of breath, blurred vision, dizziness, nausea, hypotension and numbness of the legs. Eventually it leads to fainting, which may result in death due to oxygen deprivation of the brain.
