Suddenly I experienced a mild pain in my groin area on There left leg, and within next 12 hrs the intensity of pain increased by many a times. It was to that extent that now I am unable to walk or even stand properly. I am taking tramadol IM, but only 30% gets relaxed. I have started this IM today itself. Pls advise or explain me that what is this disease. How long will pain gets subsides. As the thing is unbearable.
