I Had Prepatellar Bursitus 2 Weeks Ago And Was Thought

I had prepatellar bursitus 2 weeks ago and was thought to be infected. I lost my antibiotics the last 3 days. The other night started feeling sick with stomach problems, hot, chills and so tired that I've been sleeping during the day. Should I go back to dr? I think is have knee problem because of CRPS in foot so I am always kneeling on scooter to get around.
