"i cracked my pelvis in two places after wrecking my bicycle.  i was given tramadol hcl upon leaving the emergency room.  i have taken 1 (50 mg) each day for three weeks and sometimes 2 especially during the first week following my accident when the pain was most intense.  the most troubling side effect for  me is blurred vision.  i sleep well after taking the tramadol and am relatively pain-free for about 6 hours.  however, no more for me.  i just can&#039;t take the chance of dependency.  i will try and manage with over the counter medicines instead."
