slightly high Fibrinogen level -finger pain, lung cancer ?

Hi, 

I'm a 38 year old lady who had a slighlty high fibronogen level in my blood test, my chest xray showed i had a lung inclusion and i'm been treated with antibiotics which are not helping. I'm also suddering finger pain. NHS won't let me have a ct scan so we paid to have one done privately i'm so scared abut the results. Has anobody else had this?
