Hello. I am a 36 yo female who has been having severe joint pain in my hands, right shoulder , hips and knees for months now. I have also had non stop headaches, trouble with my memory and bilateral numbness and tingling. In January I began to have weakness in my upper arms and thighs I have been running a low grade fever for about 6 weeks. My tests for lupus and mixed connective tissue disease have come back negative and my rheumatologist sent me off saying she was there if I neededanything else, but no direction of where to go or what was wrong . Could I have either condition with the test results being negative, or what thoughts do you have?
