My promlems started few months ago.. With a cough that would not go away 2 lots of antibiotics and still no change had chest xray... Results hilar vascular prominence. Went back Dr's told them I now have swollen nodes under my arm pits and my sister previously had thyroid cancer (to which she is now fine). Gp sent me for 2ww lung.. My mind is in over Drive from positive to negative within seconds.. Had Ct Scan today so awaiting results. My question is.. With all this going on I think I am imaging other symptoms like back ache, chest hurts when breathing in, or is it that I've read up on lung cancer symptoms and my mind is in overdrive?
