I’m unsure, but I think I might have Achilles tendinitis. It’s been hurting off and on for a couple weeks, but these past few days my left Achilles has been hurting non stop. I’ve still been tumbling and doing everything at practice normally, but I’m still in pain even when walking. It’s worse when I wake up in the morning which I’m not sure why. I’ve tried stretching it, massaging it, icing, etc. Is this serious?
