New tattoo need advice

So! I got a new tattoo on thursday, 5 and a half hours. Beautiful thing. But since taking the second skin the artist applied, I’ve been suffering from inner pain, feels like head rush but I’m my arm, painful pressure type thing. I’ve been washing and creaming as per advised. Now the skin is super bumpy, really red and sore, got small white bumps in some places, like pimples. Not sure if shaving rash from before he started or it’s infected?? Really need some advice and hoping someone has had a similar experience? 

Thanks 🙂
