Got an ugly clik click BB noise on my roadie. Started very minor and after few 100s km it gradually became horrible. Convinced myself it was the BB (pressfit), and had to be replaced. Bought all tools online (expensive), and a new BB (cheap). Watched all Park Tool videos on BB etc.
But before I did the job myself (never yet removed or installed a BB myself), I went for chat to my bike shop.
Him: "You sure it's not the pedals?"
Me: "Suuuuuuuuuuuuuuure."
He changed the pedals, noise gone and all perfect now, costed peanuts.
Actually he charged me more than double what he "should" have, still happy it was not the BB (would have been of course much more expensive, and more hassle / time).
And of course a huge blow to my pride as amateur bike mechanics.
But hey, still happy....
Bottom line: if you do DIY repair, but are not really proficient, it's likely it will cost you more time, stress, and money than paying a shop.
Sad but true.
