Ok so, basically ive been playing guitar like a few hours straight in a day for the past few days, and I used to have calluses and stuff, but took a break from just everything for almost a whole year, and now that I'm back to playing, my fingers look like they might be blistering instead of callusing. This is something I'm well aware is not normal. I'm not completely sure that they're blisters, but they don't look how my fingers did when i first started playing. What do i do??

I actually just browse on my phone... i didnt know it was available on Nintendo switch, my friend just had me join lol
