Rituxan infusion folks please advise

I just had my 6 months infusion this month. 17th was the last of it. I am hurting really bad in my legs like an aching feeling. I called RA doc and they said it was from the infusion and that was just part of it. I stayed up last night due to the pain. Any advice or have any of you experienced these kinds of symptoms while on rituxan?
Thanks for any help and advice.
Hugs and Happy New Year to you all

THANKS bluejeans.... I called and talked with my dr.yesterday and they told me it was the rituxan causing the aching and hurting. Said that is a side effect of it. Thanks so much for responding to my post. I hope you and your family have a Healthy Happy New Year.
