Please! Help with my Bodybuilding/Slight Strength Routine.

So i have been doing this routine for some time now and it usually has been working out well but there have been a few issues with it and I want to know if its because of my program or is it just me. So here is my current split:

Day1: Legs
Barbell Squats 5x5
Leg Press Machine 3 sets of 10
Laying Down Hamstring Machine 3 sets of 8
Standing Calf raises machine 3 sets of 10

Day 2: Chest/Triceps
Barbell Bench 5x5
Incline dumbell press 3x8
Wide Grip Machine press 2x8
Machine Pec Fly 3x8
Dips 3x6
Pulldown extensions 3x8 with 4th set being heavier and going to 5 reps and drop setting
Dip Machine 3x8

Day 3: Rest

Day 4: Back
Barbell Deadlifts 5x5
Iso Lateral Hammer Strength Row Machine 3x8
T-Bar Row 3x8
Lat Pull Downs 3x8
Dumbell shrugs 3x8
Day 5: Rest

Day 6: Shoulders/Biceps
Barbell Military Press 3x8
Machine Pulley Lateral Raises 3x8
Barbell Front Raises
Rear Deltoid Machine 3x8
Barbell Curls 4x8
Hammer Strength Preacher Curl 3x8
Hammer Curls 3x8
Day7: Legs again and goes like this over and over. Some times there are more rest days if I cant make it to the gym. Basically my issues are that I think I want to incorporate some light lifting days because I feel like too much time passes between body parts in which i cant get enough progress. But at the same time my elbow joints get a little flared on chest days and sometimes on back days.

My goal is to get bigger and stronger with more emphasis on bodybuilding and slight on getting stronger. But a bigger muscle will be stronger regardless. I do cardio every once in a while. I have made progress on this routine but im not sure if I can get better results if I change this around or is this fine? I am just a bit paranoid that I am going to get a injury especially in my arms since my shoulders feel like they are going to snap while doing military press and my upper arms near the elbows hurt while benching and sometimes during back days and the pain dissipates by the next day. Thank you very much for your assistance
