I feel the constant need to stretch and no one knows what it is

I have a similar issue with needing to strech in my back but to do so in a way that is effective is quite contorted and odd, and what i have learned is that it can sometimes be linked to your brain making you feel the need to strech to releve stress or tension that has built up, its just a theory that me and my doctor have come up with but if you reduce the stress in your life the feeling of needing to strech may reduce, i hope this helps

I also have had that feeling over the past years. It's like I constantly need to flex my muscles all over. If your like me. I have this constant "craving feeling"
Can you relate to my feeling. Always looking for something. But can never feel the void.

It's like that. I've tried to stop stretching, but I can't go more than like 10 seconds before I have to stretch again. It's like a cough or itch. It's super uncomfortable to stop and I have to focus completely on staying still. I saw a rheumatologist about it recently and she said it was probably just a "nervous habit." I don't have either of these, but in case anyone else might...RLS(Restless Legs Syndrome) is a night disorder, and so is PLMD(Periodic Limb Movement Disorder). I hope this helps someone.
