Good evening Tom. My name is Colleen and I also had same symptoms as you except had some back pain also nothing out of ordinary. Ran out of breath climbing stairs. Went to Dr same day and was told I had aggressive NSCLC and could not get into Coborns cancer center in town here so called Mayo. Got appointments for 4 days and got the news it was stage 4 NSCLC which had metastasize to stomach and kidneys. Surgery and radiation was ruled out and chemo was my only hope. Started 4 kinds same week but after 7 months I had enough so I said I’m done. They than started me on keytruda for 2 years. Had to quit as ended up with cdiff , inflamed joints and kidneys were only working at 28%. Drank 60-70 oz water daily for 3 months and know working good cdiff cleared up and Inflammation is only thing I’m dealing with and take prednisone for that. Tumor, nodules, and cells have all shrunk.
Lots of prayers came my way and God gave me more years than they expected but one Dr at Mayo said God is in control and He is. Good luck and check in with this great group.
