I'm a Crossfitter, a mountain bike racer and i used to do a lot of running as part of my training so i feel your pain on this i had compartment syndrome in my legs (still have just not as bad) i had it terrible for about a year on my medial side and doing box jumps and double unders i think is what finally set it off, i had swelling throbbing and numbness in my feet and it finally got to the point where i started physical therapy. I had work done including ultrasound and vaso machines and then of course the other shit they do in there like rehab exercises, but i hated it cuz it was a ton of really old people and i felt out of place. it did help a little but not much, for me there were a few things that made the biggest difference in the world. I used to walk on my toes and i also have a pretty flat arch so what helped me a lot was changing my striking pattern on my feet, as well as custom orthodics (shoe insoles) id recommend them a ton! they'll cost you about 150 bucks but they last forever. the biggest help tho as much as i hated it was rest, stretching and icing them. shin splints are pretty much just swelling and the best way to treat it just like any other time there is swelling is to RICE (rest, ice, elevate, and compression…id also recommend stretching your calf, was specifically my gastrocnemious and soleus in my case) and also NSAIDS. for me yeah it sucked its been about a year and I'm just starting to bring back running, box jumps and jump rope but I can do about a mile-two with out bad pain finally for me the only thing that fired them off was any form of impact so i cut most of that out, squatting and stuff like that i didn't have to give up. but i found rest them and let them heal and then slowly work back into them to build strength in your legs again, like you said "when i go back to my normal regimen" if you take two weeks off then they feel good and you jump into a 10k there going to just swell right back up. i found i could modify a lot of things to still get the cardiovascular exercise in, for me rowing, and i didn't have a problem biking either, anytime i did a workout i just supplemented the running for rowing. another thing you could try are calf compression sleeves i wear them and they help slightly with recovery…but good luck man i feel you on this hope they get healed up in no time, iv heard some people who have them for a month then others that have them for years hoping your one of the lucky ones! sorry if grammar is a bit off did this on my phone saw the issue and i had to give you my personal experience with it, hope it helps!
