Ah well - the subforum is about voice therapy and about voce surgery and I think it helps to clarify what the topic is exactly - does not have to be in the title of the thread, but i gues sif you describe it in the post a bit more closely - it helps others.
so in your case you are doing voice therapy and no surgery but sou are self training and not with a professional voice pathologist and you experienced that weird sensation? I would say this is a warning sign then that you are overdoing it and that you may even be doing something wrong. Voice training can be a bit straining , but should only be so due to trying different stuff for a while - the voice that comes from it should not be straining, if it does it can lead to long term problems.
