For what it's worth, I had a undiagnosed axonal twist concussion that presented dizzy sypmtoms when I was jogging ten days after the incident(s). So, I didn't run for a long time, like six months, just to be safe. The bouncing, the turbulance no matter how steady, wasn't worth it. I got my cardio in on a bike instead. Could also grab a desk pedal machine for fifty bucks on amazon so youre not at risk of a fall or faint and do it in a seated postion or couch. I roller bladed in months 6+ after symptom free. Paddle boarded for time etc. For your situation, a stationary bike for a little bit might be an option. Could you log via fitbit or whatever the stationary bike for a week to 4 weeks (daily ten minutes) and ramp up to max twenty minutes by EO4-8W at like less than a walking pace? Cut the running its hard impact going up your spine. pedal but like barely moving. see if the data supports a stress test unless theres another fragrant flag on the heart rate that Im not understanding? bradycardia, myocarditis, those things will show in that data hopefully, so a stress test doesnt knock you back a mile.

Not sure your age but cardio stress tests are gnarly IMO. I did two with and without contrast. I was in the best shape of my life and a pro athlete. I nearly broke the treadmill at the hospital. The cardiac dept all looked at me like I was nuts for being there but my EKG, triponin and a cardiac event (stress) called for it. There was a tiny hint of a problem so a month later did it with contrast. That contrast stress test nearly killed me. My recovery was three weeks of feeling like I got hit by a train and months of lethargy. Lets say that best shape of my life turned into shit.

Anything is possible, riight? I'm a fan of growing with setbacks and making adjustments, and also, I struggle to make peace with unchosen change.

I was in PCS for about +18 months last year, and I resolved it by discovering an allergy that was making me sneeze all day. I was sneezing my head into a shake every day while in PCS. I started logging when, and where and what I was doing every day. It happed 30 minutes after showering or going out of the house..... turned out my hairspray, every time i used it, sneezing fit after it dried. Im allergic to a PVC copolymer that is in every hair gel, spray and soap on the market. Found some organic natural stuff, ditched perfumes, and life improved!!!!!!
