Help with bicep tendon

[BRETTY1]

Hi.It jumps at the top of the bicep its like the bicep tendon is now to long so theres movement inside.
The injury occured while doing dumbell chest press and i tryed to lower the weights to the floor while lying on my back without just droping them and thats how i stretched it.No thats correct the injury happened 2 years ago you seem surprised it has,nt healed but ive been told that when a tendon gets stretched it will never return to its normal size. Could you help me out with this one as its become a pain in the neck theres only pain when i wake up then as the day go,s on theres none.

hi, some more questions.
1.which movement causes pain? is flex/ext. of the elbow or pronation/supination of forearm.
2.What kind of pain is it? sharp, burning etc.?
3.do you have free ROM?
4.can you provocate the pain?
5. do you have any loss of strength?
6. when contracting biceps, does it look different compared to the other side?
7. is the sensation more lat. or med. in the proximal forearm?
it would be really unusual if you biceps tendon lengthens so much after stretching it. a rupture would be more common. but maybe something else is wrong!!? Lig of elbow or lig. alaria. please descibe the region and answer the questions.
cheers
