Muscle Aches an Chest pains from Vyvanse

[Swisss]

So almost every time in coming down from Vyvanse, I'm always aching and I have these sore pains right around my Lungs. I sorta have an idea why they happen in my chest, probably because I take such big breathes of air, and after awhile my lungs might stretch too much? I really don't know, but I was wondering if anybody else has these problems, and if anybody has a solution? Maybe an herbal muscle relaxer or a breathing technique? I also want to note that this definatly is not pains coming from my heart. I've had those before so I know the difference.
