When I take a deep breath, my kidney hurts.

People living in this world mainly rely on oxygen to survive. If there is no air in the world, human beings will find it difficult to exist. The main way for the human body to inhale oxygen is to breathe, so breathing is something that everyone does every day and is essential in daily life. Once a certain disease occurs during breathing, it will affect a person's normal breathing function. Some people find that their kidneys hurt when they take a deep breath. What is going on?

Skin and soft tissue infections (SSTIs) are inflammatory diseases caused by purulent pathogens invading the epidermis, dermis, and subcutaneous tissue. Common superficial soft tissue infections include furuncle, carbuncle, erysipelas, superficial acute lymphangitis and lymphadenitis, wound infection, surgical incision infection, pressure ulcer and subcutaneous acute cellulitis.

Causes

Common pathogenic bacteria include Staphylococcus aureus, hemolytic Streptococcus, anaerobic bacteria, etc., which invade areas with rich hair follicles or areas of tissue damage and cause infection. They can also be secondary to other diseases and spread through lymph or blood.

Clinical manifestations

1. Furuncle

The clinical characteristics of this disease are local redness, swelling and painful nodules, which gradually increase in size and become cone-shaped. Subsequently, a pus head appears in the center, which may burst on its own, discharge pus and heal itself. Rarely does the inflammation expand to form surrounding cellulitis or abscess. Generally there are no obvious systemic symptoms. If the inflammatory reaction is more severe, toxemia may occur, which may manifest as obvious systemic symptoms such as chills, fever, headache, mental depression and increased white blood cell count.

2. Carbuncle

At the beginning, the local area appears as a slightly raised purple-red infiltration area with a tough texture, unclear boundaries, and obvious pain. Subsequently, there are multiple miliary pus plugs on the surface of the central part, which become honeycomb-like after rupture. Later, tissue necrosis, dissolution, and collapse occur in the central part, like a "crater", which contains pus and a large amount of necrotic tissue. Carbuncle tends to spread to the surrounding and deep parts of the body, with infiltrative edema around it and severe pain. Local lymph nodes are swollen and painful. Most patients have obvious systemic symptoms, such as chills, fever, general malaise, loss of appetite, etc., and are prone to systemic suppurative infections. Cheilitis can easily cause intracranial cavernous sinusitis and acute purulent meningitis, which are more dangerous.

3. Erysipelas

The disease begins with symptoms such as chills, fever, headache, and general discomfort. The lesions are more common on the lower limbs and face. Local manifestations include redness and bright color of the skin (in the early stage), burning, pain, slight swelling, clear boundaries, the red area becomes lighter when pressed, and quickly turns red again after leaving the area. The lesion expands rapidly, and some may cause blisters, with the redness in the center fading slightly and the bulges flattening slightly. Proximal lymph nodes are often enlarged and tender. As erysipelas continues to worsen, systemic sepsis symptoms worsen, but skin and lymph node lesions rarely become suppurative and ulcerated. The disease may recur, and repeated attacks can cause lymphatic obstruction and lymphatic congestion, leading to thick skin and limb swelling (elephantiasis).

4. Acute cellulitis

Local redness, swelling, heat and pain. The redness and swelling are most obvious in the center and gradually decrease in the periphery. The boundary between the redness and swelling and the normal skin is unclear. The swollen skin feels hard and dents when pressed. Severe swelling can cause local blood circulation disorders and lead to partial necrosis. Patients often have systemic symptoms such as chills, fever, and increased white blood cell count. Cellulitis occurring at the floor of the mouth, under the jaw, and in the neck can easily cause laryngeal edema or tracheal compression, resulting in breathing difficulties.

5. Acute lymphangitis and lymphadenitis

Local lymph nodes first become swollen, painful and tender, which can be distinguished from the surrounding soft tissues, and the surface skin is normal. As the disease worsens, lumps form (the number of lymph nodes cannot be distinguished), pain and tenderness increase, and the surface skin may become red and hot. When an abscess is formed, there is a sense of fluctuation, and a few may even rupture. Acute lymphangitis can obstruct the return of lymph in the vessels and cause inflammatory changes in the tissues around the lymphatic vessels. Subcutaneous lymphatic vessels can be divided into two layers: deep and superficial (divided by the subcutaneous superficial fascia). Subcutaneous superficial acute lymphangitis appears as one or several red lines on the epidermis, which are hard and tender. As they expand, the red lines extend toward the proximal end. However, lymphangitis deep under the skin has no epidermal red line and may have a strip-shaped tender area.

6. Others

For example, acute abscess, acute suppurative infection of the hand, deep space infection of the palm, traumatic infection, etc., basically there will be redness, swelling, heat and pain in the lesion area, accompanied by systemic symptoms such as fever, chills, rapid breathing, increased heart rate, and loss of appetite.
