In hospital six months ago had picc line but in arm was very sore made them take it out bruised up a lot can this have caused a blood clot?

Yes: It can result in a clotted vein ...however it will most likely gradually open again....HEAT Packs may help! Give it a try! Hope this helps! Dr Z

Yes: Mostly these arm clots don't cause damage to the body outside the local discomfort. To be certain you can get an ultrasound exam to search for the clot or even a venogram (dye study) to identify location and size. It should. It be an issue at all 6 months out.
