Parenchymal liver disease is any disease of the functional cells of the liver, as opposed to the bile duct cells or supporting cells. One example of a parenchymal liver diseas â¦ e is cirrhosis, in which the liver cells shut off and die.
Calf muscle strains can also developed due to repetitive overuse of the calf muscles usually with running and jumping, especially if the muscles are weak or tight. Pulled calf muscles are the most common cause of calf pain in runners.ther common terms for the condition include a calf muscle strain or torn calf muscle. Essentially, what all these terms refer to is when the calf muscles are pulled beyond their normal elastic limit, overstretching them and damaging some or all of muscle fibres.
Runners and other athletes are also prone to calf tightness, as the calf muscles are constantly firing to stabilize the ankle and both absorb each landing and push the heel back off the ground. Interestingly, calf tightness can also be symptomatic of weakness elsewhere in the leg. If your glutes and/or hamstrings are weak, your calves will often try to make up for that weakness, which means the muscle gets overused, which in turn exacerbates calf tightness.
