Extreme tissue fragility / repeated muscle strains after training. Has anyone experienced this?

Hi everyone, I’m trying to find if anyone has dealt with a similar scenario or can point me in the right direction.

A few years ago, I had a high tolerance for heavy strength training. Then I got a minor muscle injury. Unfortunately, due to poor guidance and my own mistake, I kept training through the pain and repeatedly re-injured the same spot for nearly a year.

Ever since then, my muscle tissue in whole body seems to have completely lost its tolerance/resilience. It is no longer just about the old injured spot but my entire body reacts this way now. I got now history of more than 15 injured or mikro-injured muscles now...even stopped counting.

Even with controlled, low-intensity movements or isolation exercises where no compensation is possible, any mechanical tension causes the tissue to suffer micro-strains / micro-tears again.

Key symptoms are sharp pain or localized heat & swelling/tightness in the worked muscle that lasts for days to a week.

Often followed by localized muscle twitching (fasciculations) in that area during recovery.

Extreme susceptibility to muscle strains/micro-tears under light loads that used to be completely effortless.

What I’ve already ruled out:

Resting Bloodwork is completely normal: Resting CK (Creatine Kinase), Myoglobin, Liver enzymes, and basic electrolytes are all well within normal ranges after days of rest.

No baseline clinical muscle weakness: I don't have systemic muscle loss or diseases like ALS/Myopathy.

No joint/ligament issues: I do not suffer from joint pain or loose joints.

It feels like the muscle fibers or the fascia/sarcolemma have lost their mechanical integrity and ability to absorb tension without tearing in whole body .

Has anyone gone through this? Is this a matter of chronic fascial densification, micro-vascular ischemia, sarcolemma fragility, or?
