Hi after years of fighting the various issues with my body including getting swine flu and pneumonia in 2011 which left me in a coma and on life support for months. when I started to recover I got a Pulmenary embolism. This in turn left me with fibrosis in my lungs. I had a hysterectomy at the beginning of the year. Then on Tuesday I was told the 'IBS' that I was told for years that I have is actually Crohns disease. I have been given Mesalazine but am so terrified that I havent managed to take them yet. The dose seems really high and the listed side effects fill me with dread. I have a problem like i said with my lungs and am so scared these pills will cause me further problems with my lungs. I would be grateful for any thoughts on this thanks.
