It can be a cause of drug interaction depending on the drug you are taking. If you started feeling the way you are feeling after taking the drug, you should contact your doctor who many suggest that you stop taking the drugs immediately.
I have heard that people who use amphetamines can get something called meth bugs. They feel that insects are crawling on their skin. They scratch their skin until they get scars. Is that what you mean?
