Question about Achilles tendon?

im 14 and a punter and wide reciever. and recently ive been punting often and its been hurting my leg.when i jump to catch the ball or cut it gives me intense pain. at practice yesterday i couldnt put any force into my foot at all while puntin. i tried to and it felt like my leg was getting pulled in half.and thus since this i nailed my blocker in the with the ball. i talked to my team trainer and he said that it was most likely a strained achilles. i went to a chiropracter for my various other problems with my back and ankle (same one as the achilles). and as he was working on my ankle i got sharp pains. i told him about it and he said my trainer was most likely correct. so my question is. is it a strained achilles tendon? when i stretch my leg. put it into full extension. put force on my foot and lift. it all hurts, so any info would be nice
