Long story short. Ever since i was 15 i have had what i thought were 'growing pains'
so after long enough i bit the bullet and went to my GP to get it checked out explained my symptoms blah blah blah....
Whilst talking she mentioned that it could be Lupus or Rheumatoid Arthritis so sent me off for a whole bunch of blood tests.

about an hour ago i get a call from my GP's receptionist telling me i need to come in ASAP. and that they have sent off a referal to the x-ray joint and i need to go tomorrow morning.

My nan has Lupus, so im a little concerned. I know i am jumping ahead of myself but generally my GP works in the way that if you dont hear from us its all good, if we call its all bad!!
Does anyone have any information on either of these conditions?

TIA
