I'm a little older than you are and I have never had those symptoms you've had. Lots of other medical issues in my life but not like yours.
If I was you I would be seeing my family Dr. ASAP, you know it isn't going to go away quietly, correct
No one wants to here bad news, especially the persons family and survivors when the Dr. says if only they had detected the problem early
I lost a good friend to a Dr. who didn't do enough testing on a sinus problem, the Dr. ASSUME he knew enough to treat and his lack of attention for better diagnosing and testing allowed the cancer to grow and ended up killing my friend
