Sorry to hear about you not feeling well, and am glad to hear that you feel somewhat better. Upper respiratory tract infections can often lead to a feeling of general unwellness, which is exacerbated by increased nasal drainage, congestion, and discomfort. Additionally, it is not uncommon for the ears to feel clogged and even for hearing to decrease in the setting of this sort of infection. The key thing is to work with your doctor
if things do not improve in a timely fashion. With regards to blood in your mucous, it is not uncommon for there to be small traces of blood in the mucosal discharge during times of infection. The nasal airways are very well supplied with blood vessels, and the lining of the skin can be quite thin. Together, this can make them prone to bleeding
in small amounts. This should not be common, and should not persist. Many other things can also cause the symptoms that you are describing, and it is therefore important to speak with your doctor about your symptoms in more detail. Please speak with your doctor about your concerns.
