I've been dealing with this persistent cough and was put on levofloxocin 500 mg antibiotics for 5 days, but there was no relief, so they switched me to pulmocef 500. Still, the cough hasnt improved at all. I've been tested for TB, and the results were negative, no fever so far, but I do have shivering hands sometimes. I've attached my CT scan reports for reference. Right now, I'm on Tacrolimus 1.75 BD, Cellcept 750 mcg BD, and wysolone 7.5 mg OD. Is there anything else I should be considering or any thoughts on what might be causing this?
