Hi I was wondering is benzocaine can cause any circulation problems in the body for example could using it to often cause blood flow to stop or any damage

Benzocaine is topical local anesthetic that is typically applied to the skin and mucus membranes. There may be possible side effects but these are mainly allergic. It does not affect blood flow and unless the appropriate treatment of a serious side effects (bronchospasm, angioedema, methemoglobinemia) is not undertaken it is quite safe
