how long does tramadol stay in your system after you stop taking it. I only took it for about a week and didn't like the way it made me feel so i stopped. Now i've been plagued with blisters and extreme itching on my forearms after being in the sun for as little as 3-5 mins. Sometimes it's even just the warm air that starts the itching and burning with blisters. I'm assuming it's a side effect of the Tramadol but i was wondering if there is anything i can do/take to relieve myself!
