The Gemorah in Shabbos Daf 67a gives a segulah for someone who has a bone stuck in their throat to get it out. The Gemorah says to bring another bone of the same type, put it on the person's head and recite a sort of "chant": then, seemingly, the bone will fall out of place.
The question was raised whether this segulah may be performed on Shabbos. Let's say it's a fish bone that is stuck in the person's throat. May they take a fish bone (either from a plate or from the trash) and use it for the segulah? Seemingly the fish bone is muktzeh (not like bones from meat or chicken that may be given to the dogs so are not muktzeh — see OC Siman 308 Sif 27). However, perhaps one could find a heter to pick up and move the fish bone for this purpose? Is there any such heter in regards to "tlltul muktzeh" for such a purpose?
(This is all assuming that there is no life threatening situation here and that the gemorah was speaking about a case — as is my intent here as well — in which the bone is simply somewhat bothersome and not life threatening! I'm asking this as a theoretical shailo (question) in order to understand the issur of tiltul muktzeh and when a possible heter of tiltul would apply.)
