注射后血管迷走神经反应

[Sundaycandy]

我使用Reta已经四周了，到目前为止，每次注射几乎都无痛。

今天，当我在与上周不同的臀部注射时，针头的疼痛感异常强烈。疼痛到我无法将针头完全扎进去，最后不得不拔出针头，用新的注射器重新抽取剂量。即使换了新的注射器和针头，疼痛感仍然比平时强得多。注射

完毕走出浴室后，我立刻出现了血管迷走神经反应，眼前发黑，听力下降，并且感到极度头晕。这种情况对我来说并不陌生，因为我每次抽血时90%都会出现，但我注射腹股沟乳头肌时从未发生过这种情况。我

只是好奇，有没有人能解释一下，为什么我每周都按照同样的流程进行注射，这周的疼痛感却比平时强烈得多？

腹部注射可能是更好的选择。

腹部注射（例如减肥药或胰岛素）通常疼痛感较轻，因为腹部皮下脂肪层较厚，神经末梢也比大腿等其他部位少。此外，腹部组织活动较少，针头插入时摩擦力也较小。

Stomach would probably be a better option,

Stomach injections (such as weight-loss or insulin medications) generally hurt less because the abdomen features a thicker layer of subcutaneous fat and fewer nerve endings than other areas like the thigh. Additionally, stomach tissue moves less, minimizing friction as the needle enters

I have mixed feelings on this! I feel like the injection hurt less when I tried my stomach, but the site was more sore. Where the glute hurts a tad more but there is no lingering pain. I can see the point of less friction, it’s a lot easier reaching the front of me

Pain when first inserting the needle is usually from alcohol from the wipe that has not dried yet. Assuming you are using pretty small gauge needles like 29 to 31 which do not usually hurt much.

I agree stomach is usually easier and less painful, otherwise just chill out for a few minutes before getting up after an injection, and be extra careful in the few minutes after you do start moving.

Belly all day. What size syringes are you using?

I vote for dull needle. Either by the vial stopper or straight out of the pack. I've pierced the"leg" of the stopper before and used the same needle to inject. Just one time... That was plenty. Super hard to pierce the skin. Hurt quite a bit and guy a little bruise.

Smaller gauge needles definitely dull more just with regular use too in my experience. 31s actually hurt more than 29s with some of the harder stopper 3ml vials I've used. The 29 seem to hold their point just a little better.

I also vote for belly. Just easier to use two hands for me. Gently pinch the skin so you're not getting into the muscle.

I also 100% feel your pain in the vasovagal response. I used to get the exact same thing from blood draws. Actually had it a few times after Novocaine at the dentist. That first self injection for me was super tough to do.
