suggestions... sinuses are draining

Ashley 👼👼💜 • Married to my best friend with twin angels watching over us (miscarried new years day at 12w3d.)

My sinuses are draining down my throat, only it feels like it's sticking and will not come up. I'm taking Zytec and Bynadryl, but it's not working. Any suggestions on what else I can do to get this annoying feeling to go away?
