New MRI shows
There is increased T2 signal intensity within the distal aspect of the medial greater than lateral heads of the gastrocnemius muscles.
Patchy intramuscular edema within the medial margin of the soleus, peroneal, anterior tibialis. and extensor digitorum muscles. There is no muscular atrophy.
Tiny foci T2 hyperintensity involving the fascicles of the deep peroneal nerve (axial images 36 and 49 of series 6) without associated enhancement.
The bone marrow signal intensity of the tibia and fibula is normal. There is no soft tissue mass.

I looked up some of the details in your new MRI. See below. You definitely need to investigate further what may be causing your edema/inflammation/denervation and pain in the middle to lower part of your calf muscles and connecting tendons/ligaments. It seems your MRI is showing injury or autoimmune response.
T2 Hyperintensity in Musculoskeletal Imaging
Moving beyond neuroimaging, T2 hyperintensity also plays a role in musculoskeletal imaging. Common scenarios include:
Soft Tissue Pathologies: Injuries or abnormalities in soft tissues, such as muscles and ligaments, may manifest as T2 hyperintensity on MRI scans.
Joint Disorders: Conditions like arthritis can lead to changes in joint structures, often detectable through T2-weighted imaging.
Fluid Collections and cysts: Fluid collections and cysts will be hyperintense on T2 weighted sequences.
Conclusion
T2 hyperintensity is brightness on T2 MRI sequences. This is a finding or descriptive term and does not indicate a diagnosis. T2 Hyperintensity can be found on MRI scans of the entire body.
Alterations in muscle signal intensity seen in pathologic conditions usually fall into one of three recognizable patterns: muscle edema, fatty infiltration, and mass lesion. Muscle edema may be seen in polymyositis and dermatomyositis, mild injuries, infectious myositis, radiation therapy, subacute denervation, compartment syndrome, early myositis ossificans, rhabdomyolysis, and sickle cell crisis. Fatty infiltration may be seen in chronic denervation, in chronic disuse, as a late finding after a severe muscle injury or chronic tendon tear, and in corticosteroid use.
