My personal way of getting over sinus infections without any antibiotics :
Warm a couple of teaspoons of extra virgin olive oil in a microwave and on a cotton wool apply inside both nostrils. Lie down for about 10-15 min and try to gently breathe through the cotton wool soaked in olive oil. Do this procedure 2-3 times a day. While lying in bed, apply heating pad over the sinuses (make sure it's not really hot, rather comforably warm).
An ancient yoga method of nasal irrigation Jala Neti helps to clear the nasal passages and gives a great deal of relief. you don't even need a special jala neti pot, a small pitcher or a teapot will do. And mangosteen juice 2-3 oz a day for a stronger immune system, it helps to fight any inflammation and reduces pain.
Here are 3 Simple Sinus Soothers (an article from RealAge magazine):
Keep in mind that you’ll definitely want to make that appointment with your doc for chronic sinus problems. The self-care sinus soothers below will only mask them, not unearth their root cause. You should also stick with any prescription medication program you’re currently following until your doctor directs otherwise. But the following sinus soothers may be great add-ons to whatever you’re currently doing.
1 Master Your Environment
While you can’t control the world, hopefully you can control the space you occupy so that it’s kinder to inflamed sinuses. Try:
Making it warm and moist -- so your sinuses stay moist, which can aid drainage (Humidifiers, vaporizers, or a warm shower should do the trick.)
Cleaning it up -- by kicking your allergen-avoidance efforts into high gear, if you have allergies.
2 Put the Kibosh on Pain
A stuffy, runny nose is bad enough. Add pain to the mix and you’ll feel downright wretched. So kick pain to the curb right away. Try:
Applying ice and/or heat packs for relief of pain and pressure due to congestion and inflammation.
Gargling with a bit of salt water -- for relief of a sore throat brought on by postnasal drip
Taking over-the-counter (OTC) painkillers -- for sinus pain.
3 Baby Your Nose.
Whether you’re fighting off allergies, a sinus infection, or a cold, you’ve got lots of options for dealing with symptoms right away, from OTC meds to basic saline nasal sprays. Try:
Going over the counter -- for decongestants, antihistamines, and supplements that may help speed symptom control.
Limiting irritants -- like chlorinated pools, temperature changes, and secondhand smoke, to reduce nasal irritation
Getting wet -- with a saline nasal spray or a neti pot, which can provide quick nasal clearing.
Drinking plenty of water -- so you stay hydrated, which can help ease discomfort and thin your nasal secretions.
Of course, taking care of your body is a good call, too, which can help bolster your immune system. So eat right, exercise, reduce stress, and get plenty of sleep. If you do all of this, you’ve landed yourself in the driver’s seat when it comes to breathing easier.
