Cephalexin Monohydrate and arms and legs

I was taking 500mg three times a day. After 1 week I developed severe joint pain and swelling in my fingers. I got an itchy rash on the bridge of my nose and over my eyes and inside my nose. The joint pain continued to my knees and toes. I have been off of the medication 3 weeks and I am just starting to feel a little normal. a different doctor put me on 800 mg of Ibupropen 3 times a day and after reading up on the side effects of Cephalexin I began taking Benadryl which has helped a lot.

After Effects When Finished Using Cephalexin
I finished taking Cephalexin a week ago for strep throat and currently I've been feeling a tingling sensation on my arms and legs. Sometimes I get an itchy feeling on my arms. Could this be an after affect??

Thanks
