Trophic ulcer is a defect of the skin that occurs due to various inflammations of the skin, mucous membranes, and also due to a disruption in the nutrition of tissues. The area and depth of the trophic ulcer progressively increase, destroying the tissues. Usually the border of ulcers and healthy tissues can be clearly defined. However, it is possible to merge wounds that are next to each other. The appearance of red-blue spots and shin wounds always means that there are severe violations of arterial or venous circulation in the lower extremities.
- Pain in the legs.
- Increased pain in lying position.
- Pain on walking, easing of pain when stopping.
- Blue-red spots on the skin.
- Difficult to heal wounds.
More often trophic wounds of the lower leg appear when the venous blood flow slows down (for example, as a result of thrombosis or in case of varicose veins). However, they can be caused by other diseases, for example, syphilis, hypertension, atherosclerosis, purulent inflammation of the skin or tumors, and infectious skin diseases. Usually, ulcers are formed in the place of the previously injured calf tissue. Less often such ulcers arise as a result of violations of the arterial blood circulation.
Treatment of the disease
The main treatment of venous circulation disorders, which causes the occurrence of ulcers is a therapeutic compression in the form of permanent wearing of elastic bandages or medical stockings. When there is venous stasis, which causes swelling of the legs, usually prescribed diuretic drugs (diuretics). In addition, special exercises that stimulate circulation, as well as baths, are important. Later, therapeutic exercise can be used. Other treatments depend on the underlying disease.
What to do?
- Legs must be protected from injuries.
- The blood flow through the veins can be consciously stimulated, by effort of will, straining and relaxing the muscles of the shins.
- You can not stand for a long time.
- It is desirable to keep your feet raised up.
- Do not smoke.
- Do not abuse alcoholic beverages.
Usually, before the appearance of ulcers, the patient has circulatory disorders. Symptoms of such disorders can be leg pain, discoloration of the skin, or edema of the lower limbs. The doctor should be engaged in treatment. If you notice that it is difficult to heal wounds on the lower leg, you should consult a doctor.
The doctor, first of all, will assess the pulse on the vessels of the lower extremities, perform positional tests and after determining the cause of the ulcer appoint treatment. To assess the blood vessels of the lower extremities, Doppler sonography is usually performed.
The course of the disease depends on the cause that caused it:
- Trophic ulcers that appear due to hypertension are usually located in the back of the middle and lower third of the shin. If the circulation of venous blood is disturbed, ulcers appear on the inner side of the ankle. Usually both legs are affected. They swell, become heavy before the appearance of ulcers (especially with prolonged standing). If you hold your legs in a raised position, the swelling will decrease after a while.
- Trophic wounds on the leg, resulting from a violation of the arterial blood circulation, are usually located on one side of the leg. On the skin are visible blue-red spots. Particularly severe pain at night and lying down. Pain wanes if you lower your legs from the bed down.
