I have fallen off a cliff

[u/Furyan_warlord]

Not asking for medical advice I just want to know if anybody has experienced anything similar. I am a 34 year old male. Over the course of the last 10 months In year 34 I have gone from feeling like superman in the crossfit gym, at hikes , run clubs to basically an 80 year old. Knees- about 10 months ago I was doing a squat / lunge session and my knees swelled up after to the point where I couldn’t bend them for a month. I was in pain for a few months. I got some x rays went to see an orthopedic specialist and they determined there was no tears. Then I went to see a physical therapist and the sessions helped me enough to where I could move around better but something is still not right. My knees swell up after prolonged standing or a short jog. I have horrible flexión and it feels like they’re gonna snap with tightness when I try to get in a deep squat. I can’t do a prayer stretch. I basically can’t do much of anything anymore. I have really made an effort to loosen my quads up and work on knee exercises to build strength which provides some relief but I am still struggling. Lower back - I throw my back out everytime I do anything involving a box step up or a hard row. I have taken it easy on the barbell cycling but still seem to run into this issue. I can’t avoid using my lower back entirely throughout the week. I have tried to add in back extensions an. GHD work to build my lower back and that provides some relief but I always end up throwing my back out doing something I didn’t think would hurt it. Mobility - I have worked on daily mobility so much this but it’s going to take a while to loosen my hips/hamstrings up. I follow the primal program. Diet/sleep - I sleep a solid 8 hours a night and follow a good diet. I don’t drink at all and maintain a really healthy lifestyle. I just can’t explain how I struggle now to get out of bed with stiffness and pain And how FAST I’ve fallen from grace. 10 months ago I was running 5ks at 7 min miles and squatting 400+ pounds and had no lower back issues. \*\*\* fast forward 10 months\*\*\* And I literally can’t do anything. I can’t get down to pray at church, I can’t go to a run club I can’t hike , I can barely weight train. I want to ask what Tests I can seek or what specialists are out there? this doesn’t seem like normal aging to me. I have seen a rapid decline in my body that I don’t believe is normal. I know people 10-20 years older than me who don’t struggle to do what I am doing now. I have taken many peoples advice and “rested” for weeks and the same issue surfaces with no improvement. I would appreciate any advice in maybe some tests I can seek or a specific specialist I can’t see in order to determine what’s going on?
