3 weeks ago my son had a heavy cold which my dh and I both caught, it lasted for 6 days and also came with stomach cramps and loose stools, was a weird virus. A week later I began to get a scratchy throat again and blocked nose, felt run down and tired this only lasted for 2 days though. Now this 3rd week as of yesterday I woke up with a blocked nose very scratchy throat, sneezing but don't feel unwell this time. The blocked nose and throat ease up as the day goes on but never fully goes away. Ive never suffered with hay-fever or any known allergies. Does this sound like a weird viral thing or does it sound like I've suddenly developed allergies?
