Ok so I'm not yet diagnosed with lupus, but everything is pointing to it... I have so many symptoms and it's really scary.. My joins hurt constantly, and it's not just a little bit... They hurt ALOT! My hair is falling out... I have weird 'sores' on my scalp and I have ulcers... ALL THE TIME! But lately I've been developing this sharp pulsating pain in the middle of my back... Roundabout the kidney area... It doesn't hurt all the time but when it does it really hurts. I'm really worried I have a rheumatologist appointment scheduled for 1 February I've been waiting for this appointment for two months and the closer it gets the more worried I am no pain medication seems to have helped the pain and I just want it gone! What can the sharp pain indicate?
