Have been resting arms since Sunday night gonna see what happens tonight "chest day" I may end up dropping down to 250-300mg per week if i am in too much pain tonight. I am on test e 750 with nolva on hand if necessary. And yes my arms were too achy to lift my 4 yr old girl on Monday.
I had the same problem but off cycle.
I had tendonitis/ pain in my elbow.
What I did was identify which specific movements were causing the problem and identifying alternative lifts, so.....- mine were lifting the DBs when preparing for shoulder press and chest press, so I changed these movements to Barbell.
Pull ups were replaced with wide grip pull ups concentrating on using my back, not my bicep.
Machine rows - I changed the V grip handle to a wide grip and concentrated on using my lats not my biceps.
Any direct bicep work was gone completely.
Standing cable crossovers also caused pain while getting the weight from up top to chest level where I would begin my press, so I altered the angle of the cable arms to be much lower.
This let me continue the 3 weeks left until I was at my de-load week tomorrow (snowboarding in Europe, woo hoo!) without any further injury problems.
