I don’t know much about any of this but you should check if you might have asthma as my brother and boyfriend in the same month both nearly 30 just found out they have had asthma this whole time and not known my boyfriend was sure he hadn’t but always is full of mucus and had heigh fever and got sick at Christmas with a cough that wouldn’t go and it turns out it triggered asthma he didn’t know he had to suddenly become more active

do you also have trouble swallowing? almost like you forget how for a second or it takes multiple "tries" for stuff to go down?

You could try mucus thinners, it's usually a nasal spray that thins it so you can clear it out of your body. You may also consider seeing if a doctor might prescribe you a stronger allergy med to see if that helps

Lots of water. I’m a vocal coach and it’s recommend you drink 1/2 your body weight in ounces. It’ll help thin that out too. Also, a facial steamer may help. Bynadrl as needed. Stay away from dairy and excess sugars. It will cause more of that. You couod even try doing lip bubbles as it will help knock off that phlegm too. Coughing and cleaning your throat all the time will cause irritation and also cause more ick. So you could try the lip bubble to help with that itch. But definitely see a doc too and they may give you a prescription for allergy meds. Camomile tea is an anti inflammatory. Mint tea could help with those allergies too. Honey. Water with lemon.

I don't have first hand knowledge on the topic, and you have probably already tried or heard it all before, but keep your fluids up, and try other allergy relief medications (if you're able to) to see if something works better. It took me a while to find the best allergy medication for me, but over time, our bodies get immune to the medication and we need to find something else. If you have the finances and patience (I'm currently in a similar boat), go back to your GP, or specialist, even ask your pharmacist, and see what they say. If you don't get answers, try the next person. It took 10 years before I was diagnosed with GERD. I tried various medications and saw so many people I lost count. After discovering I have GERD last year, I've learnt so many other things about myself because of GERD. I'm still fighting for my health, and it's frustrating but sadly what we have to do to get answers these days. Best of luck! I hope you get some answers and relief soon!

Tea or warm water WITH Manuka honey help me so much. The Manuka honey is the key point here. Good luck ❤️

I so wish I knew of something to work. I have the same issue, except ive never really had allergies, but have had this throat clearing, mucos problem since I was little. Had pneumonia at age 2, bad enough to be in oxygen tent for two weeks, and them telling my mother if I ever got pneumonia again, I probably wouldn't survive, and do something get what yh frequent bronchitis every year... One Dr said it was chronic bronchitis, which I guess means never goes away, just goes dormant. Have you had either pneumonia or bronchitis?

I’ve had this same problem for 8 years now. I have no idea what’s causing it but I have chronic stomach inflammation and IBS. I think I may have MCAS too. Allergy meds don’t help at all and a lot of mucus comes out in the mornings. All I know is that dairy and gluten make it worse. My nose is always runny too.
