Hi and thanks for the query, It might be appropriate for you to get a proper medical examination. Other clinical signs ans symptoms like fever, weight loss, malaise might need to be precised. Any family history fo rheumatologic disorders are important to be known. An erythrocyte sedimentation rate, C reactive protein, rheumatoid factor and anti nuclear anti body testing are essential blood exams that could orient towards the actual cause of these symptoms which probably is rheumatologic (rheumatoid arthritis, Lupus, polymyalgia rheumatica etc). I suggest you consult an internist/rheumatologist for a proper clinical evaluation. Thanks and hope this helps, Luchuo, MD.
