Growthspurt at 17 or am I delusional?

I'll continue updating for any future readers. About 2 weeks in, acne has worsened for no apparent reason. I've had mild aches throughout my body and have recorded marginal growth in my limbs, my wingspan and feet in particular. (65 to 66.25 inch wingpsan, size 7 to nearly size 8 shoe size) (Though no height gain yet) I'm worried it may just be me progressively improving my form when I measure, but we'll see. I've been recording everyday as well, it's become an obsession. I highly recommend against it. Also been having emotional irritability. I feel like a kid again in some ways, not sure what's wrong with me

Hello, m17 5'5 here. Up until last year, I was borderline 100lbs (102 on a good day) thereafter increasing to around 111lbs. I've grown increasingly concerned with my height the last couple months, and have made multiple attempts to nourish myself better, apparently to no avail. Though recently, I haven't even had to try. I went from skipping breakfast, having a humble lunch and nitpicking my dinner with a few snacks in between to 2700~ calories (all healthy foods) comfortably per day - I feel I could easily eat more if my pantry permitted. I perpetually feel hungry and at no point in the day have I felt full or sated for at least 15-30 minutes. I'm about 115-6lbs right now and am wondering why I suddenly have an appetite of unprecedented size. Am I just filling out, or could this be a growth spurt? Father is 6'0 by the way. Mother 5'1. I haven't ever had a growth spurt either, so this is genuinely the first time I've ever felt insatiable
