Can a picc line cause arm pain and lil headaches that come n go I had it on the eigth and it was taken out on the ninth. But I get shooting pains arms?

Risks. A "long line" can lead to blood clots and infections. Your physician needs to be made aware of any residual symptoms, so they can address, promptly.
Unusual. Possible to have thrombosis around picc lines and arm discomfort or swelling. If a lot of clot - swelling could involve innominate veins. I am groping for a reasonable cause but unlikely. Ultrasound can determine.
