Could my symptoms be related to vaping and inactivity?

Here is all information that might be useful or help; I used to smoke cigarettes then switched to vaping 3yrs ago. Tends to sit a lot more than normal. Feeling extreme fatigue even after sleeping. Some loss of appetite. Frequent headaches. Bad teeth, can’t afford dental help. Swelling in feet & legs. It all started with burning back pain between shoulder blades, hurt more towards bottom left shoulder blade area. Chest achyness & Chest pain coming from middle of chest & goes across entire top collar bone/chest area from shoulder to shoulder. Having episodes of heart palpitations with scary feelings of panic/doom whenever it happens. Feels like a panic attack but a lot worse/amplified. If I sit/lay down & completely relax my body or go to sleep, the back pain goes away, the chest pain eases off but upon awakening my chest/arms feel extremely sore & weak. The other day I also had extreme soreness & pain in my left arm, the top backside of arm & the underside from wrist to elbow area. Top of My left hand was a bit swollen. That went away with rest as well but now that arm feels weird/sore a lot. (Didn’t know if that’s even related) Whenever I stand up for longer than like 30mins or I’m walking around, my back starts back up with the burning/hurting & my chest feels more sore/painful. The longer I’m up the worse it feels so I eventually end up sitting back down or laying down so it’ll ease off again. Also, It doesn’t hurt to breath at all.
