Yes there are a couple of things that could go wrong but, most of them can be avoided if the tattoo is done  by a professional. The biggest point of concern of many is the actual needles used by the tattoo gun. They can, if reused, cause blood carried diseases like STDs. To prevent them, be sure you ask the tattoo master to see him open a new package of needles place them in the tattoo gun before touching you with it. That's what I did to calm my nerves before making my first one.

Most other problems associated with getting a tattoo come to be either by lack of skill by the tattoo master, or lack of care by the person who got the tattoo but some are generally present and should be considered before getting a tattoo done. To prevent them, do your research and find a good, licenced professional to make your tattoo and ask him/her how to propperly take care of your tattoo when it's finished. 

The risks of getting a tattoo include:

  • You might be alergic to the ink
  • If a metal based ink is used, when going for an MRI exam , one may get  MRI-induced burns due to iron compounds in their tattoos   
  • It could hide skin cancer
  • It could get infected
  • There is a risk of getting an STD, or other blood borned diseases
  • It could affect how you sweat -> Studies have shown that tattooed skin sweats 50% less than regular 
  • If not cared for propperly it can cause scarred tissue

The top tips for caring about a fresh tattoo my guy gave me were to:

  • At all times for the next week keep a thin petroleum jelly and a bandage over the tattooed area.
  • Gently wash the tattoo a couple of times a day with cold water and an anti-microbal soap. Pat it down to remove any water, apply a thin layer of petroleum jelly and place a bandage over it. 
  • Always keep the tattooed area "wet" with the petroleum jelly and never let it dry out because it can lead to scarring and loss of pigment.
  • After a week you can stop using a bandage to cover your tattoo and leave it uncovered but still apply a layer of petroleum jelly to keep it "wet" at all times
  • For the first two years after getting it its suggested to,  if  exposing the tattoo to sun, to use a strong sun protecting creams (factor 50+)

To conclude

There are some pretty scary side effects that can happen when getting a tattoo but, most of them can be avoided by chosing a professional tattoo artist and good care of the tattooed area. I have a couple done and never had any issues whatsoever. 

Yes there are!!! Numerous ones in fact. Tattoos are designs or images made on the skin. Most people think that this is done by simply drawing the image on the skin. They feel that that's what the tattoo machine does. What they don't know is that there are tiny needles in the machine that puncture the topmost layer of skin and deposit droplets of ink under it. So what could go wrong with that, you might ask. Well

1) the ink used in making tattoos can cause allergic reactions. Especially the red, yellow green and blue ink. And while it might not occur immediately, it can still occur years after you've gotten your tats.

2) after getting the tattoo, your skin is a bit raw and open from the numerous punctures caused by the tiny needles I mentioned earlier. This leaves that part of your skin open to infection for a while.

3) sometimes, getting tattoos doesn't go so well. It can lead to an inflammation of the tattooed area called granuloma. Or it can lead to keloids which is when scar tissue overgrows and becomes very large.

4) imagine getting a tattoo and then a few days later, you fall sick and are diagnosed with an STD. It's very possible if the tattoo machine was used on someone with an STD before you and it injured the person. The tiny amount of blood can be on the machine until its used on you and poof, you have an STD.

If you were planning on getting a tattoo, I hope this helps you realize whether it's truly worth it. I'm not against tattoos but I would just like it if everyone knew the things that could go wrong.

I hope it helps

Yes there are!! Tattoos are a great form of self expression, but the risks that come with it aren't to be joked with. Here are some of the health risks and problems that come with getting tattoos

1. Possible allergic reaction: People may be allergic to the ink used on their skin and the ensuing allergic reaction may take years before it even shows up and it will come up in the form of a rash in the affected area.

2. Skin infections: Tattoos can be gateways for bacteria and harmful microbes to enter the body, especially when you just got it. You could be at risk of getting diseases like staphylococcus or even tuberculosis.

3. Keloid formation: keloids are overgrown scar tissue and seeing as tattoos are basically sort of "artistic injuries", your entire tattoo could become a huge keloid.

4. Disease contraction: If an unsterilised needle is used, then you run a risk of contacting diseases like HIV, hepatitis B and C and tetanus.

5. Swelling of the tattoo site: The tattoo site could experience some serious inflammation especially when the tattoo is healing and some people have even been know to experience a burning sensation on the tattoo area.

Overall, I don't think getting a tattoo is a good idea, but if want to get one, then at least be sure that you reduce the risk of having any of the above complications.

There are no health problems associated with getting a tattoo. Unless a contaminated pen is used on you but that is very unlikely if it's done by a professional.

Although it's said getting a tattoo might cause possible allergic reactions, luckily I didn't feel anything when I got mine, of course if you are getting a big one, might be different situation.

Don't think tattoos can cause much health problems, off topic, you might have some problems if going to Japanese onsens. I think many onsens won't allow people with large sized tattoos.
