Question: I have for 20 years had some pain and swelling in my right arm following repetitive movements, such as painting (one example). I picked up the hobby of crochet two years ago. Sometimes my hand and arm would ache a bit and the veins would get bluer and protrude a bit, but after resting it would go away. Recently I pushed through some pain to complete a crochet project. The veins began to protrude. That afternoon I sustained a blow to my right shoulder, on the edge near the rotator cuff, when a hand truck dolly fell and its blade struck my shoulder. It bruised but did not break the skin. My whole arm and hand ached for a week. The veins protruded like cords, and it has been 3 weeks now since I've crocheted. I wake up at night with my entire arm numb and aching. The forearm aches sometimes all day long. Soaking in hot epsom salt water has had the biggest positive effect in reducing the vein swelling and blueness as well as relieving the aching. However, the pain returns, localized in the elbow and radiating into the forearm. I've tried heating pad with little positive result. I don't know if I am sleeping on my arm to make it numb, but numb, aching arm is happening most nights now. Your recommendations?

I am confused how my neck or shoulder is causing the veins in my forearm especially and even my upper arm to protrude like cords, be dark blue, and cause some swelling and pain in my forearm.

the veins are on the inside of my forearm and upper arm, and they nor the associated pain go away quickly. It has taken nearly three weeks since they appeared, and I have been careful not to overuse that arm/hand, and they are still not normal. The shoulder pain has subsided, but the forearm pain and swelling is still enough to interfere with normal activity and sleep.
Is it normal for veins to look varicose and to have forearm swelling with carpal tunnel, perhaps?
