Sinus Medication Solution

I have been using my neti pot for about a month now and I haven’t had any relief. I am using the right temperature and salt quantity so I don’t think that is the problem. I use my neti pot in the morning and at night and sometimes in the afternoon. I have had allergies and sinus problems for as long as I can remember (I am 21).

Should I give up on the neti? What else can I try? I do not want to take pills and nasal sprays have not helped me.

Thanks.
