Are Mild Chest And Abdominal Pain Due To Vyvanse?

I m 25, 165 lbs and 5 foot 2inches. I have been taking 50mg of vyvanse for just over a month. I smoke weed in the evening just before bed. Recently I have noticed mild chest pain along with mild stomach pain. Is this something I should worry about? Does the weed effect the vyvanse in my system? Before vyvanse I would occasionally pick at my fingers, cuticles and bite my inside cheeks and lips. I realized more recently after being on vyvanse that I bite my inside cheek and lips almost non-stop all day. My jaw is becoming sore all the time. I also noticed that I can spend a up to a few hours in the evening, and throughout the day pick at my fingers and cuticles. With my fingers if I see something I need to pick I can t stop thinking about it or focus on anything until I get it. I also have a weird thing about certain textures touching my hands, and I have to wear knee high socks almost all the time because the feeling of My lower legs touching my pants makes me crazy. I don t want this to consume my life or get any worse. But I also don t want lose myself by taking more meds. Where does these impulses come from? And how can I get rid of them before they consume my life even more or ruin my relationship?
