I was just researching about torn and pulled muscles and found that a second-degree tear was very similar to what you explained. If you had been doing physical activities this is a possibility.
I Have Trouble/pain In The Right Leg, Above The Knee. Not Sure If It Is The Muscle Itself...there Is A Definite Lump, Although Nothing Seen On Scan. Pain Is Now Worse Than Ever. Any Suggestion?
The pain in the right leg can be due to trauma, injury, accidents, sports injury, over weight, muscular pain or it can be due to a pinched nerve. I advice you to have MRI of spine to investigate as all other tests re not showing any thing.
