Hello. I was diagnosed at 30 and began on Ritalin quick release and ER… then graduated to low dose Concerta. I felt amazing on Concerta, but I also noticed right away a certain amount of tightness in my chest that I attributed to an increase in blood pressure. Within a few months, I noticed that capillaries were bursting on my face (which I am permanently sad about now). My doctor switched me to Adderall and then to Vyvanse as adderall seemed too intense in terms of peaks/crashes. So far no more scary chest tightness or burst blood vessels. Hope this is helpful.
