Hi and thanks for the query, the fatigue and fever described especially at the level of the shoulders deserves exclusion of a particular clinical syndrmome. This is called proximal musle weakness and accompanied by cited symptoms suggests a disease called polymyalgia Rheumatica. Tests like erythorcyte sedimenation rate an a full blood count are required to prro a chronic inflammatory process and exclude tge fact that anemia is not the cause of your fatigue. A clinical evaluation nby a physician to actually ascertain and monitor your blood pressure levels, control urine once again and do a general clincal evalaution is worthwhile. I suggest you bok an apiontment with an internist for a complete evaluation. thanks and best regards, Luchuo, MD.
