From your history it seems that you have got multiple problems with multiple systems involved.
You avoided the problem thinking it is virus.Who told it is viral origin ?sometimes one becomes his own doctor ! I do not say it is not virus but as you avoided the treatment thinking of virus.
Now in your nose secondary bacterial infection took place resulting pain,inflammation,swelling etc causing all problems.
As you have hemorrhoids it can not be viral origin,it is altogether is different problem.
And about rash
it may be of some allergy
or due to your presently existing problem.
Consult your family doctor and discuss in detail of all problems go according to his advice
ok and bye,take care.
