My cousin has been suffering from peculiar issue that offlate she feels Stifness in muscles with severe pain and she can't even walk. It happens twice or thrice in a month. This is happening for the last 5 years. We have consulted many hospitals but not cured.Doctors confirmed it's not arthritis. Someone said it's food allergy. But till date it's not cured. Earlier she used to get bumps at knees ankles and thighs. But now only sweling and stiffness in muscles are seen can any one Help. Which specialist we have to meet ESR value is 85mm/1hr
