The time it takes for torn muscle fibers to heal depends primarily on the severity of the injury. You can find out which periods are common here.

If the muscle is torn, the first treatment is rest. Because muscles need time to recover. If reapplied too early, there is a risk of more than just severe pain. The injury can also get worse. How long complete rest is necessary and when you can start exercising again depends primarily on the extent of the tear and the part of the body affected.

After a muscle fiber is torn, it often takes several weeks for the affected part of the body to regain strength. If there is a small tear, the injured person, in the best case scenario, can begin training again with caution after a few weeks. If the muscle fiber tear is more severe, the healing time is expected to be longer.

However, only an orthopedist can provide an estimate of the expected healing time after he or she examines the torn muscle fibers.

Muscles usually take several weeks to fully recover. But he doesn’t have to be completely immobile for that long – on the contrary: As has been shown, it would be beneficial for regeneration to start doing light exercise again as soon as possible, as long as the pain allows.

Usually, complete rest is only needed for the first three to five days. After that, isometric exercises are often the first rehabilitation measure. Muscles tense without moving parts of the body. An orthopedist can explain which exercises are suitable and how to do them correctly. Alternatively, physiotherapy may help.

It is important for those affected to pay attention to their own body: If an exercise causes pain or other discomfort, it may be too early to do it. In this case, it is best to have the wound checked again by a doctor.

Healing does not always go as desired. Sometimes regeneration takes longer, so it can be frustrating, especially for those with sporting ambitions. If the pain does not subside or barely subsides even several days after the injury or even worsens, it is advisable to seek medical advice again.

However, ignoring the pain and starting training again despite this is a bad idea: pain is generally a warning signal when muscle fibers are torn. This shows that healing is not complete and the muscles have not fully grown back to carry out their duties. Any premature strain can worsen the injury or cause further injury. Once a muscle fiber has been torn, it is important to avoid any activity that causes pain – although it requires patience.

As soon as the pain subsides, exercise helps improve muscle mobility and ensures the muscles quickly regain their usual resilience.

Healing time for torn muscle fibers is usually several weeks. Exactly how long the affected person will be unable to train depends on the severity of the injury and other factors. After an injury, the body begins to repair the tear. To support this process, the affected muscle groups must be spared first and then retrained with specific exercises after three days at the earliest. But only if the pain allows it.
