I finished doing hammer curls and right after i get this weird annoying pain on the upper part of my left bicep near my shoulder...

i used to work out about 2 years ago for almost a year and never felt this pain ever b4,

i first got this pain 2 weeks ago after doing hammer curls, and i missed my next 2 workouts because of it, it took about 5-6 days for it to heal and on the following week after hammer curls it didnt hurt at all but I did them yesterday and it's hurting again now.

any1 know why this is happening?
