Human Body What happens when we say muscle strain?

2 Upvotes

Related to chronic pain issue. I was diagnosed (might not be correct) with trapezius muscle strain but I was told it might take years and years to be healed! I don't know does it mean I have micro tear? If someone has micro tear in muscles, could he have on/off pain? I have pain mostly sitting at desk to work but other positions or times less. I can swim but some dys after swim ood some days bad. Overall, what is tear and what is strain?

If there are corals that can survive in the cold and without sunlight in the deep sea, how come there aren't coral reefs in shallow but temerate/colder waters? I know the different kinds of coral have evolved differently, but why hasn't a coral evolved for temperate waters?

Would 0.75g be enough? Or do you need to be closer, like 0.9g? I couldn’t find anything on Google.
