I've been "morally beated up" because I didn't suffer from injuries for years - typically not even during my PL competitions - and I'm getting all sorts of troubles now with F1, which is suppose to be "safe". My knees still hurt, I guess it's the meniscus. Hamstring injury is just over. Hope this is going to get better. I'm looking forward to improve.
You are progressing too quickly. Your connective tissue needs time to adapt to the new stresses. Just because your muscles can do the movement does not always mean you should go to the next level. If you are having joint pain you need to keep the reps the same until your connective tissue adapts.
