Sorry to hear. Some things sound common, unfortunately. ER visits can run to 8 hours to 2 days here. Sounds like you could have been infected when the port was accessed by medical staff not following sterile protocol or something else, and assume they did a blood culture? I learned not to speed up any hospital discharge, and when it's time, it's time, and all that aftercare should have been worked out with the social worker before leaving. Maybe it was a home care attendant that was sent, as opposed to a visiting nurse, who is licensed to do more. Having had staph, MRSA, sepsis, the antibiotics were given for a much longer duration, like 10-20 days, I forget, but was no two days. Some places even take the port out. I would see your doctor for follow-up, call the social worker, and if any signs of infection are present, go to the ER. Good luck.
