Sir. I am 31 years old. 5.6 height & 57 kg weight. Three months back I load apx 12 kg weight & walked upto 3 km. That day I felt little bit strain on my right leg knee. After that I used feel often little bit pain. Three days back I went for evening walk for 4 km and next morning I felt severe pain on my knee (little bit upper side). I find in internet there are quadriceps tendons on knee cap which supports the load while we put. I tried some massage exercise with mustard oil as seen on youtube with my thumb & next day the pain was completely gone. I might think due to long walk without taking food through out the day fatigued the tendons. Sir please help me to write if again I will have to run or walk, will I get again this pain because it had never happened before. Thanks alot.
