The disease manifests itself by water retention on the ankles and is accompanied by red spots on the lower legs, which represent reactions of the veins and the skin to the disease.
To support the veins, compression stockings are usually worn in the therapy of venous insufficiency.
For more information, see Chronic venous insufficiency.
Inflammation of the blood vessels becomes medical Vasculitis called. Vasculitis can occur anywhere on the body, regardless of where the veins are located or how large they are. Depending on which blood vessels are affected by the inflammation, a variety of symptoms can arise.
The symptoms of vasculitis result from the fact that the affected blood vessels can no longer supply certain organs with sufficient blood.
Making the diagnosis of vasculitis is very difficult in many cases because the disease is very complex and varied. Red spots or spots on the legs can be a first and decisive indication of such an inflammation of the blood vessels.
In addition, there are accompanying symptoms such as severe weight loss, general malaise, Joint and muscle pain, Vision deterioration or Numbness in the legs.

This is done through a Inflammatory responseat which it too Pain, swelling, and redness can come. The skin may become red and itchy, but not itchy either. Joints can swell and hurt, which means that their movement is restricted. If left untreated, an anatomical change in the joints can occur, which means that the usual movement can only be carried out to a limited extent even without a rheumatic attack.
In the event of a combination of reddening of the skin and joint pain, a physical examination should also always be carried out Blood count be made. In the case of a rheumatic disease that leads to the specified complaints, would be Inflammation values (CRP, leukocyte sedimentation rate) elevated. The so-called rheumatoid factor can also often be detected as increased.

If rheumatism values are normal, an infection-related cause is usually a diagnosis of exclusion. It is also important here other accompanying symptoms, such as.

If an infection is suspected, treatment would initially only be symptomatic. A antibiotic treatment would initially be carried out cautiously.
In the case of a rheumatism-related cause, anti-inflammatory drugs as well as drugs that reduce the immune system can be treated. This group of drugs includes the Cortisone, which can be taken for several days to weeks in the event of an acute rheumatic attack (Cortisone in joint diseases).
Today there are also newer drugs, the so-called Biologicals, prevailed in the treatment of rheumatism. Before any rheumatological treatment should be started, the diagnosis must be proven.

After a sauna session, some areas of the body's skin become red and indicate overheating in this area. At these points the body has not been able to counteract the heat from the sauna. The skin turns red because the body widens the blood vessels at this point so that as much blood as possible is transported to the overheated area for cooling.
Red spots usually appear on the face, but can also occur on the legs or arms.
Even if the heat is too great and the body sweats a lot, it can happen that evaporation is not possible due to the high temperature in the sauna. The next and last possibility to cool the body is to dilate the blood vessels, which is noticed by reddening of the skin. Reddening of the skin during and after the sauna is normal, but accompanying general symptoms such as dizziness, nausea and headaches should be observed in particular and the stay in the sauna should be ended if necessary.
After leaving the sauna, there may also be a compensatory influx of blood, i.e. it may be that there were no red spots while visiting the sauna, but these suddenly appear heavily on the body and legs after leaving the sauna. Here, too, it is about cooling measures of the body
If reddish spots form on the legs after or during extreme heat, this may be due to a build-up of heat. Normally, the body tries to cool the body down by producing an even sweat when the heat builds up too high and to achieve a constant body temperature.
If it does not succeed in this for various reasons, small heat islands can develop. These islands are small, demarcated areas of the body in which the temperature is higher than in the surrounding areas. The skin in the overheated area turns red because the body widens the blood vessels in this area in order to bring as much "cooling" blood as possible into the overheated area. Viewed from a little further, this results in clearly visible red spots.
The heat build-up can be counteracted by going to a cooler area relatively quickly after the skin reaction has occurred or by cooling down the reddened skin with cooling compresses.

If red spots appear on the child's legs after or during exposure to the sun, this can be the first sign of sunburn. Although sunburns are usually more extensive, it is also more common that sunscreen has already been applied to the skin and some free areas have then been burned by the sun, which can lead to a not uncommon blotchy appearance on the legs.
Furthermore, the skin can be irritated by the sun (preliminary stage of sunburn), which would also result in blotchy skin changes. Sunlight allergies can also cause red spots on the legs.
The child should first get out of the sun to see whether the red spots remain on their legs or go away. Furthermore, depending on the symptoms, cooling compresses should be applied.

This can either be a rather harmless irritation of the skin caused by the sunlight (a preliminary stage of sunburn) or a strong overheating of the legs from the sun. In the case of overheating, the body would try to widen the blood vessels in order to transport as much blood as possible to the overheated area to cool down. Under certain circumstances, this can also produce reddish spots.
Sun allergies can also be behind a patchy change in the legs.
Regardless of the triggering cause, the baby must first leave the sun and be brought into the shade. Then you can see whether the reddish spots have receded and whether there is a direct connection with the solar radiation.
It is important to protect babies from exposure to the strong sun. Sun protection includes protection from covering clothing on the one hand, and protection from sunscreen adapted to sunlight, which should be spread over a large area on the skin.
