Hi there ~
I understand your concerns. The continuous chest pain
is concerning and the headache is a common symptom of injection meth
use. I also believe that you are feeling dizzy and lightheaded due to using IV meth. I strongly advise you to consult a psychiatrist
or a local qualified doctor as soon as possible to get your medical concerns addressed and get rehab treatment for substance dependence
I hope this helps. Take care and have a lovely day!
