The people at the plasma centers were always very nice, professional and competent. I'm just touching on the idea that there is a stigma attached to getting money for plasma. Well, whether that's deserved or not, there are not any reasons why I should tell our questioner today not to give plasma. But you did warn against becoming a regular. Repeated venal puncture is never a good thing.
All veins wear out after many uses.
Of course the plasma centers use main, large veins, so it would take lots and lots of uses, but over time, especially if there are technician slip-ups, that vein too will wear down. I used to get really dehydrated after donating. I am sure the donating center told you to drink plenty of fluids both before and after your donation. Young people, college age people can replenish fluids very quickly. So really, that's not much of an issue.
