forearm/ ulna length

my ulna length (length from tip of olecranon process to middle of bony protrusion on the pinky side of wrist of right arm) is pretty much exactly 10in maybe give or take .2in. The forearm length from olecranon process to beginning of hand is probably like 10.5in.

Now ive been really concerned with my forearm length thinking it looks weird all the last few weeks but im not really sure if thats the proportion problem i'm seeing with my body or if there even is such a bad problem. It could just be BDD.  All I know is that when I hide my arms behind my back my proportions look way better and I look way more like a proper adult rather than a 165cm person. This doesnt necessary have to be forearms, it could be humerus but I doubt that would be as apparent under clothes and just in general. I'm  also overweight, probably about 165lb but dropping weight pretty fast now cause I want to see If it makes my proportion better, and also have never worked out my arms in my life


Im wondering if this needs to be addressed. At the end of the day im willing to do pretty much anything, but my current plan was to do 8cm femur lengthening in the next two or three years, then do 4-5cm humerus, then pause and think if I want to go further (which I would expect to) and go for the tibias. However, I'm now considering a modest forearm lengthening of like 3cm with dr. Salameh, or whoever is in a respectable country who will do it. Yes I know it is risky, however I cant function properly knowing I dont look right, so I find the odds to be in my favor, as long as the risk isnt very high (lets say above 2% of meaningful permanent injury.. maybe)

I just hope this isnt necessary, I was content with my current plan. I just dont know if humerus lengthening will properly solve my issue or just make my arms look even worse by having one long segment and one short segment.

Is it possible for a 25.4cm ulna to occur in people around 5'8 or 5'10? It seems like everyone irl has longer forearms but obviously I cant directly compare and I cant rule out that im just freaking myself out

Now lets all take a moment to reflect on the stress we go through and pain and everything just to get what most people have completely handed to them and take for granted... I cant even imagine it.

My wingspan is 177 cm, I am yt, my BMI is 19, my ulna length measured as per your method is also 25.4 cm, my fingertip to top of AC joint bony prominence is 76 cm, no one has ever considered my arms to be short, nor do I tbh.
I roll up my business shirt to elbows every day at work, it displays my low BF, musculature and masculinity imho.
I was 171 cm tall, now 179 cm tall after 8cm femur CLL, my sitting height is 93 cm, inseam (crotch to floor) is 83 cm, my proportions still look good.
