What could this be? comes and goes over the past 4 months?

I've read this up on the internet and it seems so many people have the same problem.

I suffer with anxiety, so dont know if that could be something to do with it....But one day, about 4 months back, i felt like i couldnt swallow anymore, like i had been strangled. My throat was really tight and then i developed like a lump in the back of it. It disappeared after about 2 weeks. Then it came back after another few weeks...(it was more severe in the beginnin, i still have like a lump feeling but more like a dry lump). So now i get it very often and i just feel like i cant get enough water although im not thirsty its just the dry lump makes me feel like i constantly need water.

The weird thing is that sometimes the feeling completely dissapears, even when i actually do have like a lump in my throat (the very same day)..............So i really dont know what it could be? Has anyone got any suggestions? or maybe experiencing the same thing?.....Let me know, i appreciate it.

Thankyou in advance :)
