Phenylephrine
"I have read so much about this medication not working. But I don't suffer from a runny nose or congestion exactly. I have allergies that make my sinuses swell shut, and its very painful. Other than good old benadryl, there is no other medication that is even slightly effective for me. I'm curious to find out if anyone has used it for a similar problem and had positive results. All I have seen is that it's a placebo. And I can say with confidence, that is not the case for me."
