Hey guys. First time here
So it’s my 2nd month of beginners PPL from the r/fitness subreddit in Reddit. I was doing dips (first time doing dips BW. I previously just did the Dip machine) and then all of a sudden my elbows got fucked (now I learned it was my Tricep tendons and not really my elbows). I went to do a set of Pushdowns, but I just couldn’t. Happened 2 weeks ago.
Now my legs. I started feeling it after I got trucked in gym class and landed hard on my knee, but I would’ve thought that my injury would be because I’d over stretching and straining of the tendon. I also felt a lot of pain in trap bar deadlifts (never doing those again). This happened about 1.5 weeks ago
I’m not convinced that this was a build up from previous workouts and trying to go heavier than I can because it started after trying out new excersises. Not just going mindlessly heavy on ones I already do.
I’ve been out for about a week now. I went yesterday thinking my pain was gone, but to be safe I deloaded, but nope. Not gone yet 
Any further solutions?
