Hi littlewish, sorry your having problems with your viens. Just a suggestion, some things that make the veins not work are dehydration, this seems to be a big problems with senior citizens, they never are hydrated enough for them to start IV's . Also maybe something like vitamines that helps to strength veins, Vit C with bioflavinoids, another product called picnoginal (spelling) might be wrong. Thats suppose to be super biflavinoid. It can't hurt to take extra vitamines, especially when were sick we don't always eat right. And I'm sure that some of those meds deplete you of essential nutrients. Take care, hope someone else can help you the the vitamine department. Patricia
