For the past year or so I've had real trouble eating although at times its not as bad as others but the past week or so i have barely eaten a thing and I'm starting to worry. I'm either just not hungry at all or when i am hungry i don't fancy anything and if i can get some sort of meal in front of me i can barely touch it before i feel sick Or full! I'm constantly tired and just have no energy or motivation to do anything. Is this physiological or something more. Would just like to add It's not that i want to be thin because i hate how i look at the moment and all my family and friends are telling me how skinny i look. I want to put some weight on but i can't!
So, you are not eating due to lack of appetite and you are losing weight.
Why not see your GP as a few routine blood tests could go a long way in answering your questions.
P.S at the same time get him to look at the "lumps" in your nose.
