• Knee pain?

Hello my name is Matthew. Exactly 8 days ago, my right inner knee began bothering me with pain, stiffness, and swelling. Now it is much worse especially when I first wake up out of bed. Ironically, my right shoulder is painful for about an hour mainly when I attempt to raise it. I did fall about 7 weeks ago but I had no problems until now which may not even be related. If you could just give me your opinion or some advice that I may ask my doctor, I would appreciate it. I'm worried that this may be an autoimmune arthritis disorder because of how it progressed and, I was diagnosed with Guillen Barre Syndrome in 2011 which you obviously know is an immune disorder. Thank You, Matt.
