| Intermittent claudication (calf) | Calf muscles | Cramping pain | After same degree of exercise | Quickly relieved | None | Reproducible |
| Chronic compartment syndrome | Calf muscles | Tight, bursting pain | After much exercise (e.g., jogging) | Subsides very slowly | Relief speeded by elevation | Typically heavy-muscled athletes |
| Venous claudication | Entire leg, but usually worse in thigh and groin | Tight, bursting pain | After walking | Subsides slowly | Relief speeded by elevation | History of iliofemoral deep venous thrombosis, signs of venous congestion, edema |
| Nerve root compression (e.g., herniated disk) | Radiates down leg, usually posteriorly | Sharp lancinating pain | Soon, if not immediately after onset | Not quickly relieved (also often present at rest) | Relief may be aided by adjusting back position | History of back problems |
| Symptomatic Baker's cyst | Behind knee, down calf | Swelling, soreness, tenderness | With exercise | Present at rest | None | Not intermittent |
| Intermittent claudication (hip, thigh, buttock) | Hip, thigh, buttocks | Aching discomfort, weakness | After same degree of exercise | Quickly relieved | None | Reproducible |
| Hip arthritis | Hip, thigh, buttocks | Aching discomfort | After variable degree of exercise | Not quickly relieved (and may be present at rest) | More comfortable sitting, weight taken off legs | Variable, may relate to activity level, weather changes |
| Spinal cord compression | Hip, thigh, buttocks (follows dermatome) | Weakness more than pain | After walking or standing for same length of time | Relieved by stopping only if position changed | Relief by lumbar spine flexion (sitting or stooping forward) pressure | Frequent history of back problems, provoked by increased intra-abdominal pressure |
| Intermittent claudication (foot) | Foot, arch | Severe deep pain and numbness | After same degree of exercise | Quickly relieved | None | Reproducible |
| Arthritic, inflammatory process | Foot, arch | Aching pain | After variable degree of exercise | Not quickly relieved (and may be present at rest) | May be relieved by not bearing weight | Variable, may relate to activity level |
Falls from Height is Knwon to cause major morbidities and mortalities. There are several prognostic factors for survival that have been identified: Height Age Type of surface Body part that touches the ground first Two other factors are important, but do not have a significant effect on mortality: Circumstances of the fall (suicide, accident, escape) Initial impact with an object before impacting the ground Height . Overall, about half of victims die at the scene, and a total of 70% die before they reach the hospital . The median height leading to death is about 49 feet, or about 4 to 5 storeys. 100% of victims die after falling 85 feet, or about 8 storeys. Age . Mortality increases with age due to pre-existing medical conditions and decreased physiologic reserve. Type of surface . The type of surface struck (i.e. grass, water, construction debris) can also have an effect on secondary injuries and survival. Mortality after striking a hard surface is nearly doubl...
