Im new to this site , three and a half months ago ( and off work on the sick ), i had very bad pains in my chest and back , i also smoked 20-30 fags a day . went to docs had blood tests and told i had a lung infection and possible blood clots , had injection in my stomache for blood clots and a CT scan , stopped smoking straight away , CT scan showed no blood clots ,but i had a pleural infection on my right lung , told it was pleurasy , given a course of antibiotics. went back to consultant had another x-ray and CT scan , the infection had turned into a solid mass , given more anti-biotics and steroids . had more blood tests and x-rays and another CT scan the infection had cleared in my right lung , but i now had an infection in my left lung ( pneumomonia ) . was sent for a pleural affusion biopsy , also more blood test x-ray . was told i may have auto-immune desease, which has stopped the anti-biotics from working . all this time still having the same chest pains and breathlessness . been back to work for a week and a half . Consultant now sent me for heart scan and a lung capacity test .I have been given a blue inhaler and a brown inhaler , these help to open may air ways , but they are not treating the infection . my lungs feel like they are half filled with concrete and only half of my lung is getting any oxygen , need something to clear the infection , and just one lung full of fresh air would be good . getting very concerned about this now !!!!
