Im sick of seeing people jump on those who seek genuine advice about medical problems. If you dont want to give advice then shut up!! Why scream 'Go to a doctor you fool!!' They are often just looking for some reassurance, often because they have to wait a day or two to see a GP. My opinion= if you have nothing helpful or constructive to say, then dont say anything!
And guess what...some of us DO have medical knowledge and years of experience, I feel I have a lot to offer in this respect and it is the only reason I stick around. I can think of at least three others who appear to do the same.
