In one sentence, describe what the following article is about:

soleus strain. With a more serious strain, it's important to distinguish which muscle is involved to the greater extent: the deeper soleus or the more superficial "heads" of the gastrocnemius. MRI or diagnostic ultrasound may be needed to best diagnose the location and degree of the injury. Grade II strains involve more extensive damage, up to 90% of the muscle fibers may be torn. These injuries present with more pain (described as sharp in nature), significant loss of muscle strength and range of motion. Swelling is more severe and bruising quickly develops because of the internal bleeding from the torn muscle fibers.  With Grade II strains, there's limited ability to perform activities, especially jumping and running, so you'll be sidelined for a while (a few weeks or more). The gastrocnemius muscle is considered at high risk for strains because it crosses two joints (knee and ankle) and has a high proportion of type-2 fast twitch muscle fibers  The medial head of the gastrocnemius muscle is strained more often than the lateral head. treatment protocol. This protocol is still appropriate for Grade II strains, although you may have to keep the ice on your calf for a little longer (up to 20 minutes at a time) if the deeper soleus muscle is the primary site of injury. Instead of using R.I.C.E for a few days as is the case with a mild strain, more severe strains will likely require attention for a week or more.  Most Grade II lower leg strains cause significant discomfort for between one to two weeks post injury, depending on proportion of muscle fibers involved and the type of treatment sought. These types of muscle injuries may require one to two months before a complete return to athletics occurs.  For moderate to severe muscle strains, the use of anti-inflammatories should be restricted in the first 24 – 72 hours due to increased risk of bleeding from the anti-platelet (blood thinning) effect. A Grade II strain is a relatively serious musculoskeletal injury that most likely involves significant scar tissue formation, as well as noticeably reduced range of motion and strength. As such, after the swelling, bruising and pain have mostly subsided, ask your doctor for a referral to a sports medicine specialist or physiotherapist who can offer a variety of tailored strengthening exercises, stretches, massage techniques and therapies such as therapeutic ultrasound (to reduce inflammation and break down scar tissue adhesions) and electronic muscle stimulation (to strengthen muscle fibers and promote blood flow).  Return to full activity is usually allowed when you're pain free, have full range of motion of your lower leg and full strength of your calf muscles, which may take a few weeks or more.  Calf strains are most common in men between the ages of 30 and 50 years.

Summary:
Differentiate between gastrocnemius vs. Utilize the R.I.C.E. Seek out physical therapy.
