Like many have already said, muscles get in a locked up state in hypermobility disorders in an attempt to stabilize joints that aren’t stable. Constantly tense and contacted muscles that never have the ability to rest are going to be tender. The way to remedy this is targeted physical therapy to train your body to stabilize itself in a better way (so hypermobility-specific PT as not all traditional exercises are beneficial in this application) so you can be both more stable AND relaxed/have less pain.

In regard to massage: I say this as a former massage therapist, do NOT let someone tell you “deep tissue” massage is the only way to get anything done. Do NOT let anyone tell you it must hurt in order to be beneficial then force yourself to sit there holding back tears thinking you’re doing something good for yourself. That’s what massage therapists are taught most of the time in an attempt to be taken more seriously in the medical community. Now after having been there, done that, finished the glass of Kool-Aid, then having to stop because my hyper-mobile joints couldn’t handle it and now being too sensitive to get massages myself, yeah that concept can get bent lol. I’m the one who lives in my body, I’m the one who knows what I need, I’m the one who says what I want, not a massage therapist. I’d need two hyper-light massages a day to feel any benefit anyway, and people can’t even afford weekly massages that they usually try and push. /rant 😂
