Singulair Bloodpressure, Sameday, Ear Infections, Googling, Asthma

I am 16 and have been on Singular since July 9th of this year and the only side effects that has been affecting me that I really notice is the ear infections and headaches. my mom and I think that I might have one right now but have not gotten the chance to make a doctors appointment. The other side effects that I read about while googling it were a sore throat and upper respiratory infections which are both things that I have been fighting since March, which is what lead to me being diagnosed with asthma. In response to the person that was talking about asthmex, I also got put on that the same day and the only side effect that I had from that is a higher blood pressure that usual but it was still in the normal range, caused by the steroid in it.
