[|Human|] When I injected I didn t think I missed the vein. It didn t really burn. It swelled up instantly its been maybe over 24 hours and it is pretty swollen , red and pretty painful.. But it s also stiff but very sore all around. It s hard to stretch my arm all the way out. I ve been tryin to google my symptoms but I ve seen so many different things.. I m not a frequent user it was just recreational stuff. So I have know idea what to expect. What do I do
[|AI|]  Hi, I had gone through your question and understand your concerns. Pain, redness,swelling in the arm vein after injection are mostly due to thrombophlebitis. With such case in my clinic, I will reassure the patient telling him that this swelling will fade with treatment. I suggest doing duplex Ultrasound for his arm, Using cold fomentation, also I suggest receiving systemic and topical anti-inflammatory medication, suitable antibiotic, NSAID.
