I had a lot of pain during FUE. The anesthesia was not working during the implantation. Is that normal?

Pain during your surgery is not normal.  Surgery should be done with pain free anesthesia.  If the doctor is experienced, they should be able to offer a pain free experience.

It sounds like the anesthesia was not being kept up with to prevent break through pain. This could have been from over use of anesthesia and long surgical times. Or it could have been because you are a high intense exercise person and you were burning the anesthesia off quickly. However your yield should be fine now that the procedure is over. If you have another procedure, make sure they know beforehand you have difficulties with anesthesia.

Some patients have low threshold for pain and can also metabolise the anaesthetic material faster. So you need more of it frequently. This does not reflect in the outcome if everything else was done well.

If your doctor is experienced, they Would know the distribution of the nerves and numb the area without problems. An experienced doctor knows how to handle this situation. 

I have seen this rarely. Some people just seem not to get a hold response from either the xylocaine or the marcaine that we routinely use.We then switch to other sytemic medications. This just happend recently, so very rare. Maybe this person who commented in the one who experienced this as it would be a cooincidence considering both timing ang geography. I welcome a conversation with you about it.
