you are having nasal infection
which is leading to serous otitis
media (fluid accumulation in the middle part of ear ,behind the drum).
You must not blow your nose otherwise the infection behind your nose will enter your ears and the problem will increase.
you have to take---
Tab. Ebastine/Loratidine/Acrivastine + phenylephrine/pseudoephedrine
two times a day
Tab. Acetylcystiene (Mucinac) 600 mg once daily
Nose drops 2 drops both nostril 2 times a day
blood came our because you have traumatised your ear canal by Q tip.
PLEASE DO NOT USE SUCH THINGS TO CLEAN YOUR EAR , IF THE Q TIP WILL GO DEEP INSIDE SOMEDAY THEN YOU WILL DEVELOP EAR DRUM PERFORATION.AND THEN YOU MAY REQUIRE SURGICAL TREATMENT
