I Was Hospitalized For Sepsis And On Antibiotics Via IV

I was hospitalized for Sepsis and on antibiotics via IV for 4 days and then oral for 2 more weeks. The day after I finished the last antibiotic, I had pains in both m y legs and it has been about a month and still have the pain. It is extremely painful to sit and stand up, and to go up and down stairs.The worst is when I have to get up from a sitting position. I m trying to find out if this is a result of the Sepsis or long term antibiotics and is this permanent.
