Flying with my pump for the first time and have questions

Hey sorry I never updated! Here’s how it went for me. I told the lady before going through that I was wearing a pump and she instantly told me I would need to be patted down. They took me aside and did a total pat and wand down on me while they also throughly went through my bags. Then the lady had me pat down my pump and swabbed my hands. After that pad was tested she let me go, thanking me for my patience. My mom told me they also took the pads all through my bags.
I’m just wondering was all this needed? It sounded to me like many people have had it easier then that so I was not expecting all that. It was a small airport so maybe thats why.
I’d love to hear back from you guys again!!

I have never had any problems with TSA. I leave it on and they never know. Its not like its illegal! They usually dont even know i have it on because i hook it on to my bra… but i just leave it where it is with out hassle.
