Inflammation of a section of vein, often just under the skin, with clot formation in the afflicted part. This can occur after a minor injury to the vein or as a complication of varicose veins or Buerger’s disease. The affected blood vessel is swollen, tender, and red, and feel hard. Malaise and fever can also occur. In certain cases there may be an underlying deep vein thrombosis, and an ultrasound scan may be carried out to check for this possibility.
If there is an underlying deep vein thrombosis, treatment is for this cause. Otherwise treatment involves support with a bandage, non steroidal anti-inflammatory drugs and, sometimes antibiotic drugs.
The condition usually clears up in 10 – 14 days.
