Hi There, thanks for asking. As you mentioned there is a relation between cocaine use and vascular events. Most of the problems are related to constriction of the vessels which can manifest themselves with numbness
and tingling. The best way to help it is not to use cocaine again. If tingling sensation
still remains after cocaine discontinuation, some medications like pregabaline can help improve that unpleasant sensation which could bother more at nights and interfere with your sleep. I wish you an enjoyable life.
