Hi!
I am sorry to hear about your medical problems. X-rays cannot detect muscle and ligament tears. For this you need a MRI. Meanwhile apply ice packs for 10-15 minutes two to three times a day. Raise your leg, do not bear weight, take non-steroidal anti-inflammatory such as Aleve or Mobic and consult a doctor. Take care!
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
