Testicle feels bigger than the other

[Khan_z]

when I sleep or sit at the side that side of testicle becomes bigger or feels like it has swelling than the other one. if I'm at the right side, then right testicle will be affected, if I'm at the left side then left testicle will be affected. If I stand then they'll return to normal.No discolouration, no pain nothing. So what and what not I'm facing here? it's been happening for a month now.

There's no way of knowing what you're facing here because it may not be anything, or it may be serious.

Do you feel any lumps?

This has a good description on how to do that - https://ro.co/health-guide/check-for-testicular-cancer/

You really need to see a doctor, even if you don't feel lumps. It may just be the way you are sitting, but it could be something serious, so don't delay it, and just go. Let us know.

No, I don't feel any lumps.  Well as far as going t the doctor, I don't know. Fear creeps up on me or something whenever I think of getting doctor's help.

Not going to the doctor won't change what it is, just the outcome of what it is.

If it's something serious, your doctor can treat it and give you the help you need. If it's something serious and you don't go, the outcome is not good.
