Finger tip

Guys is it just me or has anybody else has experienced a weird feeling on your finger tips when applying monoxidil

I have an ok beard (yes do use it for hair growth not recovery) but i want to make it better And i started applying monoxidil foam for the last 4 days

Besides that i can also detect a weird sensation on my heart

Asking for advices on what to do I seriously think about stopping applying for good
