I've gotten horrible sinus infections my whole life. This actually sounds interesting since you say it makes your nose run. Here is my personal list of tricks/advice.

FYI: I am not a doctor and these are all things that have seemed to work for me over the years. Try not to kill your self with my advice. You'll make me feel bad, and nobody wants that.

1) Your body does a crappy job of handling sinus infections. If you leave it all up to your body you will end up feeling horrible for several days. The midway point is about when you are at your worst with a fever, This is when your body is finally doing something about the infection. Your body is an idiot

2) Your nose is stuffy because it has a large ball of infection in it. See other people around here talk about it. It's super gross but such a relief to see once you expel it out of your nose. Oh you had sinus infections and you never saw it? Well remember how the nose and throat are connected? It's likely that you ate it. I once vomited because I ate my sinus infection on an empty stomach, Good times.

3) Most meds hurt more then help. Your #1 goal is to get the infection out of your nose. The only way you can do this with out a wacky sinus vacuum (My ENT doc actually used one of these. So awesome) is by losing it up with water. I've found that things like sudafed just stop your nose from running so this gives your infection a chance to dry up and dig in more. You may feel better for a little bit but in the long run it makes it last longer. This is why your nose is running in the first place. All that clear liquid snot is your nose trying to push out the infection.

4) WATER WATER WATER. Long hot showers, tea and soup for the steam. Spicy food for making your nose run. Get a humidifier that boils water to make steam and that has no filter for things to grow on it.

5) If you want to go at this with everything you can get a sinus rinse kit. I use this one http://www.amazon.com/Ayr-Saline-Nasal-Rinse-Kit/dp/B002UFUIWS This is REALLY effective but you need to be careful, if you use water that has stuff in it you could give your self a worse sinus infection. Some one died this way recently, I'm sure you can find the story around here. Use water that has been boiled recently (let it cool. DO NOT PUT BOILING WATER IN YOUR NOSE) or recently opened distilled water (If it's been open for a while things might be growing in it.).

6) You can tell it's coming. Nose stuffy? Feeling a little slow? Sore throat from post nasal drip? It might be that time again. use tips 4 and 5 to fight it off before it gets bad. This can be done but you need to see it coming.

7) Don't over do it. Do not blow your nose like crazy or over dose on meds. Chances are it will not help you, you may even hurt your self. Take your time and try to relax even though you are a fever ridden mouth breather with a throbbing headache for a few days.

8) Know your snot. Clear: Your nose is running to get something out. Expect this a LOT early on. Green/Yellow/White: You got some infection out, Now is the time to celebrate. I hope it was big enough to give you some relief. Red: Blood. Green/Yellow/White + Red: This last bit seems to be where the infection was eating the wall of your sinuses, so chances are this is the end of the infection. Keep hydrated to be safe and get the last little bits of it but you should be able to return to your normal life in the next day or two.

EDIT: I no spell good.
