Bleeding at the injection site

Just did my testosterone injection and the injection site bled immediately after and is now sore and bruising. What went wrong? That’s the first time that’s happened.

It’s possible you hit a capillary. Be sure to ice it to help with soreness.

I had bleeding today too for the first time when I took my first MIC B12 😬. The needles for the intermuscular 💉 are no joke! I think I went too deep.

Sounds like we all hit a bad spot today lol 😅 I did my IM micb12 injection in my thigh today and it bled so bad! It’s never bled so bad and it’s now sore and bruising 😩 idk why it’s so hard sometimes to find the right spot! I like when my husband is home from work on the weekends because he can help me with my IM shots in my hip. ♥️

I’ve been doing injections for years and I often hit a vein if I use my thigh

Hi Jennifer! A little bleeding and bruising usually just means the needle nicked a tiny blood vessel under the skin, which happens to almost everyone now and then. Gentle pressure right after the shot helps. If the spot gets very swollen, hot or more painful over the next few days, sign in at joinbelle.com and message your care team in the patient portal.
