i there. I have been suffering for about three months now without a diagnosis. My symptoms are as follows: pain in upper abdomen/chest on right side (worse when i breathe), it is painful when I swallow and breathe in upper chest by the middle slightly to the right, jaw muscle/throat pain right side, swollen throat lymph node right side, neck pain right side, pain in between shoulder blades right side, completely inflamed right shoulder, pain that shoots down arm sometimes, right side pain under armpit, joint pain throughout my entire body mainly arms, and heart palpitations. My grandma has Lupus and I seem to take after her because I feel ill a lot. I am also sensitive to the sun, it makes me feel like i am going to pass out (mainly when it is hot). Does this sound like I might have lupus, pleurisy, both, or possibly something else? My chest x-rays and cat scan came back normal. I am a 24 year old female... please help me, I feel so ill. thanks :)
