- Varicose veins generally cause inflammation. Symptoms: painful, hard and swollen veins, erythema, fever, shivers.
- Thrombosis occurs when blood clots develop in veins that lie deep within the limb, the obstruction reduces the metabolism of tissues which can cause ulcers. Medical treatment is needed. Causes: circulatory disorders, blood coagulation disorders and varicose veins are its predisposal factors. Symptoms: aching leg, swollen leg, contracture, erythema, tense, shiny and cool skin or fever. Treatment: staying in bed, blood diluents, bandage.

Consequences: loss of sense (smell, taste, heat), numbness, spasm, weakness of muscles, dystrophy or paralysis.
Sudeck-syndrome: caused by the serious sprain or fracture of the upper or lower limb, the repeated replacement of dagger ends, malfunction of autonomic nervous system caused when a plaster-bandage has been applied incorrectly the consequence of which is the veins are involuntarily seized with cramps and due to the bad blood supply an atrophy of bone and other tissues may begin to develop.
