Tissue healing by fibrosis can be better as the scar tissue builds quickly and bigger, re generation will only grow to what condition the muscle is left in, ie if it is cut, tissue will grow both sides, but scar tissue or fibrosis will bridge. Tissue will grow onto the scar tissue and even replace it.
Scar tissue can form for a number of reasons, not healing properly, infection, improper surgery
Applying heat to scar tissue can help increase blood flow and promote healing, but it may not necessarily "loosen" the tissue. Scar tissue typically forms as part of the healing process, and its structure is different from normal tissue. Heat can help make scar tissue more pliable and reduce stiffness in the surrounding muscles and connective tissue.

Granulation tissue:the tissue that normally forms during the healing of a wound. This tissue eventually forms the scar.

Dense fibrosis refers to an excessive growth of fibrous tissue in an area, typically as part of the body's healing response to injury or inflammation. This results in the formation of scar tissue that is thick and tightly packed, which can lead to loss of normal tissue function or restricted movement. Dense fibrosis is common in conditions such as chronic inflammation, fibrotic disorders, or following extensive tissue damage.
A cicatrix is a scar left by the formation of new connective tissue over a healing sore or wound.
Another word for scar tissue is "fibrous tissue." Scar tissue forms as part of the healing process after an injury, replacing normal tissue with a denser, less flexible material. This fibrous tissue can develop in response to cuts, surgeries, or other forms of trauma to the skin or internal organs.
A keloid is made from an overgrowth of scar tissue that extends beyond the original wound site. It is a type of raised scar that occurs when the body produces an excess of collagen during the healing process.
there is swelling because the scar tissue is damaged its the body's way of healing it
Granulation tissue is a type of connective tissue that forms during the healing process, typically in response to injury or inflammation. While it can develop near a nerve root, it is not the same as scar tissue, which is a denser fibrous tissue that replaces normal tissue after injury. Granulation tissue may eventually mature into scar tissue, but they are distinct stages in the healing process. In the context of nerve roots, excessive granulation can potentially lead to complications such as nerve entrapment or irritation.
