Question

I have not felt well for the past 5 months. It started with wieght loss for no reason, swollen lymph nodes, night sweats and some chest pain. As time went on, the chest pain has gotten worse, I have shortness of breath all the time and I have headaches every day. Also, I have pain in my bones a lot, too. I get a shooting numbing pain every day going down my left arm. My doctor has done quite a few tests and she cant seem to figure it out. She's done a chest xray, pulmonary function test, ct scan of my chest, an electocardiogram and an echocardiogram and a holter monitor. These last few tests were because she found a new heart murmur and because I have PVCs all the time. All of these tests have come back normal which is great- but I have no answers. I've never had shortness of breath and I've never smoked. Do you have any idea about what could be going on? Also she did my bloodwork and that has all been normal except my calcium was a bit low. She tested my thyroid, too- normal. Thanks!
