A pinched nerve is an uncomfortable condition that may cause shooting pain, tingling, and discomfort, particularly if it occurs in your back, spine, or hip. A pinched nerve occurs when too much pressure is applied to a nerve by surrounding bones, muscles, or tissues. The pressure interrupts proper nerve function, causing pain, numbness, and weakness.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
