See a doctor.
It is rare but there have been cases of inflammatory myopathy as a complication post tattoo - it's been found in cases where people are immuno-suppressed - which could be for a number of reasons.
I say "have been cases" - a quick google only brings up one - so it seems very rare - or under-reported.
Not saying that's your issue of course - as above - you should see a medical professional (internet forums are not the best place to get any kind of diagnosis).
It's only 4 days old and and yeah it still hurts quite a bit im having pain next to it but I know that's probaly normal and yeah the spots are to do with the tattoo I do have eczema too but that would be more notice able to the eye. I'll have to go to the doctors to see what they advise. It seems a couple of areas on the tattoo have started healing nicely but the rest of it hasn't followed suit
Dude. I don't know how to be more clear. I got a tattoo. I started having muscle pain under the tattoo and the ink itself started to hurt in the same way a sunburn would hurt. It was out of the ordinary. I'm not crazy or stupid. There is a definite causality.
