Sounds like you need to ease off for a bit. I would. Do some more stretching etc if your not really doing it often. I honestly forget to do it enough, but when I'm stretching and foam rolling at home for about 30 mins 4 or 5 times a week at night. I absolutely feel better all over. Less aches and pains etc. The key is actually putting aside my time to do it.
And honestly don't go balls to the wall trying to gain strength ALL the time. I do a ebb and flow type thing. I'm not afraid to take 3-5 days in a row off every other month. I know some guys are thinking I a huge fucking pussy right now. Train 7 days a week your a lil bitch! lol. But hey, its how I do it, all of our body's are different, I'm not blind to my own limitations. Otherwise with gear, AI, dry compounds, pushing to the extreme all the time. Bound to snap some shit up.
