Suddenly joint pain

[Gab122]

I woke up with considerable joint pain today. It's where my right leg connects to my hip. I haven't had any joint pain prior to this. First infusion was a week ago. Figured I'd staved off that symptom with early dx and treatment. Shd symptoms be popping up?
Gab.
Update: Just walking around 5 min seems to have slightly diminished pain. I imagine when I take my prednisone it will help too. (Waiting as I Just took my Prilosec.) Am more concerned that new symptom popped up than about the actual level of pain.
2nd update. Ok. Weird. Pain is gone and I haven't had pred yet. ?? Just slept on it wrong?
