Asthma or not? feel chest and throat tightness...

it all started just this Januay, I am a female, 20 years of age. I began to experience short breaths and dry cough. As the days and weeks passes i began to experience back pain and headache. At night, during short breaths, i began to notice/heard this whistling sound when i exhale,. This March, i developed a congested nose because of the cold weather i guess. and after one or two days i got cold...I was diagnosed with sinusitis at the age of 13.
I started to take nasathera and solmux mucolytic, my cough worsen and also the whistling sound especially at night, sometimes i feel that my chest and throat tightened. So i stop taking those meds.
until now, during at night, sometimes i feel chest and throat tightness. I also cough but only when it is a cold night or when i eat food that makes my throat itchy. I still heard this whistling sound. I am now taking xzyal after supper.
My mother told me that when i was a baby i was brought to hospital and stay there for 1-2 weeks. I was given nebulised salbutamol. All i know i was brought to hospital because of too much cough and runny nose. My mom forgot if it was asthma or bronchitis i was diagnosed of. She also told me that she always brought me to beach every early morning, and my beddings must be always changed a very week. as i grew up i i always have this runny nose almost every month.

Thanks...
