some help please

Okay so i got my first tattoo in 2007 and it was fiine . now just about month ago half of it is itchy and bubbling and scabbing like it is new or something?? i do not see a bug bite and its not the whole tattoo anyonee have any clue to what is going on with it ?

There are alot of variables unknown that need to be considered before you can make a clear diagnosis. what color ink is under or near the inflamed areas?? and does it itch at all? Has it gotten better or worse since you first noticed it? Do you have any known allergies? things like those can all contrinute to this. I would suggest taking an over the counter antihistamine on a regular basis as directed on box for two weeks, if the problem persists we will know its not an allergy. Ok?

lots more variables here also.have ya canged any of the following? diet meds lifestyle body soap laundry soap. any new meds or food geographic location,extra stress body lotion drinks. see what i am saying here. so many different things. try some benadryl for a while if doesnt go away seek med advice as we are not doctors.best of luck keep us informed.
