I initially got cold for few days after taking cold medicine(chestonCold) I felt better but it's been more than one month I am having blocked nose. I occasionally get sneeze very rarely and dont get cough but I could see little blood only in morning  from past few days while clearing throat and through out day I don't get any phelgm. Due to blocked nose I am having difficulties in taking deep breaths and I don't have any other  previous health issue or known allergy. I don't feel any fatigue but I am worried as it's not getting well even after months. Please suggest if I need to take any medicine.
