jane, I had thisi for three weeks constantly, came on suddenly and after food it was stuck and could not force it up. My husband gave me some alka selzer once and it nearly killed me. Never again. Then it disappeared and I can burp again so this might be temporary. It will happen not very often now and if it does I drink a small cup of warm water in sips. I also notice that it was better if I cleaned my teeth so wondering if the peppermint helped. I know peppermint relaxes the LES and can make it worse but for me it was soothing and I burped!! Have you tried Peppermint Tea, many swear by it for after dinner to help food digest. But others cannot tolerate it. I never tried it as water helped me. Also, I found when it was stuck and I went for a walk it moved it. Also a tight bra causes havoc and needs to be loosened. Unleash the "girls" and see if that help.
Feeling this for you as it drove me mad - but it did just disappear so this could be the same for you.

Thank you Gwen, here's to hoping it disappears for me too. It's been constant for about four weeks now. And yes walking seems to help.

It's funny you mentioned brushing your teeth- I thought the same thing! I asked myself the other day - why do I always feel better after brushing my teeth?! Haha so maybe yes I will try the peppermint tea but will start with those warm sips of water

Thanks for confirming you had this too so I know I'm not crazy! : )

I swear by peppermint tea it now only unsticks the burps but settles my stomach when i feel nauseous. peppermint candy also is good for my syptonms.I did stop wearing underwire bra and that helped a bit.\Hope this is helpful :)
