Problems with veins

[LookingforAnswers15]

Hi,

I was wondering if anyone has a similar issue. I have noticed before that a few doctors have said that they have problems inserting needles into my veins. They said that they keep wiggling or they burst once the injection is inserted. Over the weekend, I ended up in the Emergency. I think it had to be celiac because I ate some gluten free food for the first time and I was throwing up so much. I swore that I won't buy anything prepackaged ever again. This was like a flashback to when I was so sick that I ended up in the hospital because of dehydration and I was finally diagnosed with celiac. Now, my hands and arms are filled with wounds because a doctor yesterday and a nurse today could not give me i.v. fluids. Both of them said the same, veins are wiggling, moving, visible but once they insert the needle they move. While we were talking yesterday, the doctor said she had a patient who has lupus and similar thing was happening to her. It goes without saying that I freaked out. Is it possible that this could be related to lupus? Those who know me on this forum from before, know that I have been worried about other AIs because I have had some symptoms that I thought i should not have since I am on a strict diet. I think it is time to start looking at things again. I am so tired of doctors and being scared. That is why I decided to take a break from looking for the answers on my own. I do not think anyone understands what I am going through at home so it makes it harder. 

If you know anything about veins and why this happens, please let me know.

Thank you!
