I have the same experience with exertion. There are theories about the scenario being investigated and proposed in the medical professional right now and clinically research is underway with new NIH funding. So many of us are literally disabled. People try different self -help mitigators and share what works for them. Our condition is similar to what was previously called "chronic fatigue" syndrome. And since COVID-19 is relatively new, there's much to be discovered that's specific to this virus. Most Drs in regular practice aren't familiar with the very wide range of ost-COVID symptoms, many of which are vague and/or intermittent. Drs focusing on this syndrome are discovering new things every day. But clinical trials are required before treatments are definitive for application There's much trial and error for sufferers trying whatever is within our reach on our own. So many of us are in the same boat as you are. But then there are people reporting restoration. The treatments that helped them are also diverse. There is hope. I believe we will have something uniform and effective soon. Be kind to yourself and preserve your energy. Maintain hope until then. 🙏 We have an online community here, which is a great resource and support.
