I really would like to thank you all for the suggestions and help.
During the evening (I really can't explain why) the pain "went down" to the forearm and no more in the bicep.
This morning the forearm/bicep is 70% ok but the real pain is in the high lat (near the spine) always on the right side.
Very strange, never happened to me.
In any case it seems that performing heavy barbell exercises is only hurting me as I grow old.
Maybe it's time to switch and go for DB only.
Thanks again to all of you guys.
Your Super Mario
