Can achiles tendonitis feel like sharp pains? pains have been constant like a sore muscle now they are sharp all when i walk or move it in circles.

Yes: Is you achilles tendon tender and/or swollen? Other causes of pain in that area are bursitis and heel spurs.

? partial tear : This could represent a partial tear of the achilles tendon although tendonitis by itself can be sharp pain try hot / cold packs back and forth maybe wrap it with plastic wrap at bed time (this is an old horse trainer trick) if pain continues you will need to be seen for evaluation.
