All my bone joints are rubbing each other and my muscles become very weak and feeling very coldish inside all the muscles and freuently with vomtings and feeling poisinous inside the whole body. I am suffering with this unknown disease for the past 10 years. All types of blood tests were done, x rays MRI and all reports shows nothing abnormality. Day by day i am becoming like skeleton. No doctor has recognised my abnormality yet. One of the doctor advised tissue fluid culture test. What is this test and how it is performed. Any use for me by undergone that test. Please help me and suggest some other deep tests to find any infection inside my muscular system.
