Welcome to Mayo Connect, where many of us understand exactly what you mean when you say +"...I'm really tired of it all..." We are patients and caregivers who have also been there, or are there now.

What is the difference between nocardia and pseudomonas? Both are bacterial infections that attack people with weakened immune systems. Both are treatable with antibiotics, but several tries may be needed to find a combination that works and that you can tolerate. Some of the antibiotics may need to be delivered by IV, and some courses of treatment can take from several weeks to many months.

Have you seen a doctor who specializes in treating infections specifically?
