Hey lovely!
So I have the following piercings, I will rate them by my personal pain & healing process!:
Philtrum - this one was quite a painful facial piercing. Around 8/10. The healing was a little rough, lots of swelling. But by far one of my favourite piercings.
Septum - honestly minimal pain on this one! 2/10 when getting it pierced. Healing was a breeze too. I forgot it was there haha!
Labret - this one was probably 3/10, healing was quick and quite painless too
Conch - pain was more so a 4/10, healing was longer as it is through cartilage but as long as I didn't sleep on my ear it was fine!
Tragus - pain again was around a 4/10, but the healing process was a bit fussy. Sometimes flares up with pain if I sleep on it.
Venom (double tongue piercing) - this was about a 7/10 getting pierced, but my god, the healing process was awful. I really do not recommend getting this one if you have not had any other piercings before! The healing was a long process, and I couldn't eat anything more than fluids & puree's for weeks until the swelling and pain had gone. It was a lot of pain. But, with all that being said, it is my most favourite piercing out of them all!
All I would say is that you should research the piercer you are planning to see, look at reviews and make sure you have a consultation with them if they offer it to see which piercings may work for your anatomy
Piercers should use implant grade titanium, preferably internally threaded jewellery
But genuinely go for it! I love my piercings and they are such a fun way to express yourself!
