So I've got roughly 6 weeks left of my summer holiday off uni to continue bulking. I began about 3 weeks ago. My current split is as follows

Chest/Tris (A)

Incline DB bench press
Flat BB bench press
Dips with Tri focus
Skullcrushers

Shoulders/Tris/Legs (B)

Standing Military Press
Upright Row
Squats
Calf Raises

Back/Bis (C)

Barbell Rows
Deadlifts
Curls
Hammer Curls
Chins



I do everything roughly 3 x 8. I have pretty much no other major physical exertion and i'm not working, so the way I split this routine is to do A and B on consecutive days, break, do C, break and repeat. Essentially training each muscle every 5 days or so. The problem I'm having is that I seem to be getting injured. I'm getting pain in my elbows when doing curls, and I can not do barbell curls at all due to shooting pains down the inside of my forearm (flexor carpi ulnaris?). My shoulders and right knee both have little niggles and I seem to be cramping up more, with reduced overall flexibilty. Now I had all this slowly developing before i started bulking properly while at uni and lifting, starting maybe 2 months ago, but I feel it's got worse.

My question is what to do? Should I reduce my workload/week and training each muscle group less frequently? My diet is relatively good, I get in about 3000 cals a day of mostly clean foods. I'm eating about 150-200g protein/day (I weigh 175 pounds) and i'm getting a lot of sleep (infact I'm finding myself more tired in the morning after 8-9hrs sleep, whereas in the past I would feel fine on 6.5-7 hrs).


edit: I was ill for a few days about 2 weeks ago and I've still got 'the sniffles' which may account for some of my problems?
