The signs of all blunt injuries include pain, swelling, bruising, and restricted mobility - which vary in severity depending on the shape and severity of the injury. However, bruising and strains can cause different symptoms. These are presented below.
Pain as evidence of bruises and strains
Bruises are particularly painful. Sometimes they cause more discomfort than if there is a break at the appropriate place; typical example here is the rib bruise.
The pain is the result of soft tissue swelling, often accompanied by bruising, in which the skin swells and turns blue or purple, but does not rupture. An injury is not always visible from the outside, especially when deeper vessels are affected - treacherous and especially dangerous if the bruise, for example, affects internal organs. In the bruise as well as in the strain pressure and strain cause pain.
Bruises and sports
Very unpleasant, however, among the frequent sports injuries is a bruise of the muscles as the bruise forms between the individual fibers. Strong pain, immobility or paralysis of the affected body part can be the result. Partly it comes to muscle hardening.
Some sports, such as handball or football, carry a high risk for the so-called horse kiss, a painful bruise of the thigh. On the other hand volleyball players often suffer from a bruise on the knee. Also bruises on the foot, back or shoulder often happen during sports and sometimes cause an effusion in the joint. Bruises of the bones are associated with great pain, but they relieve relatively quickly.
Longer, however, remains the high sensitivity of the skin. Since the symptoms of bruising and fracture can be very similar, the latter must always be excluded by a specialist.
While bruises occur as a result of impacts or blows, strains are usually the result of quick, jerky movements. It leads to overstretching of the individual muscle fibers and damage to the connective tissue. Also, a strain usually happens during sports, especially in neglected warm-up training. Strains of the thigh or calf are particularly common.
The strain causes sudden, stabbing pain. The painful restriction of movement is particularly evident in the use of the affected part of the body and prevents stretching of the muscle during muscle strain, while the ligament strain prevents movement of the joint.
The pain can disappear completely at rest, for example in the ligament strain. The bruise may be visible or palpable. This also depends on the severity of the strain:
- A slight strain on the calf, for example, causes only minor discomfort when under stress, which feels like a cramp.
- If individual fibers are ruptured, a stabbing pain immediately appears, the bruise becomes visible after a few days.
- If several fibers or even bundles are affected during the strain, every movement hurts.
