sinus problem perhaps?
i used to have it.
then i took spirulina and my condition improved.

i also consulted an ENT (Ear Nose Throat) specialist at Pantai Hospital back then and all he gave me was a nasal spray
(which could be so conveniently bought from pharmacies)

my sinus problem was quite bad.

my nostrils would be blocked almost all the time. i had to breathe through my mouth.

i had constant headaches especially at the area right between the eyebrows.

i used to wake up feeling very dizzy every once in a while. i cannot even stand when that sorta dizziness strikes.

sometimes, i get terrible headaches which make me feel like my head's gonna explode.

however, now i'm feeling much better. remember, don't ever try suck the mucus back into your nose. blow the mucus out. sucking the mucus back into your nose frequently would result in headaches and promote sinus problems just like what i used to have.

p/s: a nasal spray clears any blockage in your nostrils thus allowing you to breathe better

spirulina, which is also known as "lang zhou" is definitely not expensive.
i wouldn't say that it's cheap either but it surely is affordable.

there's this guy selling spirulina products at the garage sales.
good prices for the products he sells.

other than the nasal spray, i did take some doctor-prescribed pills for my problem too (just remembered).
after that, i started taking spirulina.

however, although the long term use of nasal spray is bad for health, it provided me with instant clearance of the nostril-blockage.

for those with sinus, Spirulina is highly recommended.

my aunt and dad had sinus problems too but thanks to spirulina, they're now ok.

i've stopped taking that product for a few years now and yet, my sinus problem has not returned.
i still get a headache or two every once in a while but i'm much better now compared to last time.

oh btw, i've no links with the spirulina company or anyone selling em haha
