Welcome to Health Care Magic. I understand your concern.
Even though you already know that consuming Methamphetamine
has a lot of side effects, let me mention some of them.
The side effects can be categorized as either physical or mental. The symptoms you are mentioning are physical side effects of meth use.
In the long term usage, meth use can cause irreversible physical harm: Permanent damage to blood vessels, including those of heart and brain (leading to bleeding), high blood pressure
leading to heart attacks, strokes and death, increased heart rate
and blood pressure; damaged blood vessels in the brain that can cause strokes or an irregular heartbeat that can, in turn, cause cardiovascular collapse or death; and liver
and lung damage.
The swelling of your hands and feet could be also a side effect of methamphetamine usage.
If I was your treating doctor, i would recommend you join a rehab centre, and start living a healthy live.
Hope I answered to your question. If you have any further concern, feel free to ask again.
