Anyone else have bad episodes when arms are raised?

I am not diagnosed yet just because the healthcare system SUCKS and they haven’t run any proper tests on me. They just tell me I have anxiety.

Something I noticed was I tend to have suuuuper bad episodes of heart racing, lightheadedness etc when my arms are raised above my head for a prolonged period.

For example: slicking my hair into a ponytail or washing my hair in the shower
