Ligament injuries to the PCL, LCL, MCL, and ACL are painful and debilitating. Knee pain relief often requires surgery and then physical therapy or rehabilitation. For amateur and professional athletes alike, ligament injuries are sometimes difficult to detect. A loud snap or pop followed by a feeling of looseness in the joint is a telltale sign, however.
For less serious ligament injuries to the knee, medical treatments begin with the RICE method, an acronym for the words rest, ice, compression, and elevation. Anti-inflammatory painkillers like Advil, Aleve, Tylenol, and Motrin can also help with the swelling and provide knee pain relief.
