So results from CT back and thank God not Cancer. Still bit of a mystery though so being refered to Respiratory Medicine at the hospital as "Mycoplasm" term used :
Mycoplasma is a genus of bacteria that lack a cell wall around their cell membrane. Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic. Several species are pathogenic in humans, including M. pneumoniae, which is an important cause of atypical pneumonia and other respiratory disorders.
So more blood tests and sputum samples till get hosp appointment. Just to add to it also GP said enlarged bile duct seen ( No Gallstones though) so going to have ultrasound of Liver too.
All a bit exhausting but I know why I was feeling so unwell since January now
