Hi everyone my name is Liz and I have had a recent chest x ray that has revealed a shadow on the bottom of my left lung. I am waiting for a CT scan and the worse thing for me is my mind feels muddled. I recently had a chest infection treated with everything. Diff biotics and steriods. I work full time andI am never still for long only recieved the phone call from my doctor yesterday. The hardest thing really is concentrating. I have a responsible job but havent been the sharpest knife in the box remembering stuff like I normally do
