Hi there ~
I understand your concerns. The painful blister
in your tongue after the use of methamphetamine
is likely due to the substance use. Difficulty in swallowing and puffed up face may also be related to the same condition. I also believe that you may be affecting your kidneys and damaging them to the point where you might need medical attention. I hope you consult a doctor as soon as you can to get to the path of recovery.
I hope this helps. Take care and have a lovely day!
