Why don't you give echinacea a try? I was having terrible sinus pain and pressure, and was very miserable from January this year!!! I've been taking Nature's Bounty Echinacea for two weeks now, and I feel absolutely wonderful, I haven't had a headache and it feels great!!
I'm even starting to exercise again, which I used to do but haven't done for about two years, fighting these sinus infections off and on. I've been taking two tablets three times a day (400mg) and now I find that I can just take two a day, and still feel wonderful!!!! Give it a try, it's not expensive and it might just give your immune system the boost it needs!!
I was awful dizzy, brain fog, tired, bad headaches, and miserable to the max!!!, I didn't want to be bothered by anyone, not even my husband and son, now I go outside and play basketball with him and take him to the playground, something I haven't wanted to do for the past year, just wanted to stay in bed all day and be miserable!!! It's a great feeling, I made up my mind I was going to beat this without drugs, that made me feel even worse, so I did some research and decided to try herbs, and well I feel almost 100% better!!!!
I'm going to continue for the eight weeks, and then give them a break.
