I've been taking 40-60mg hydrocodone 3 times a day for a little under a month due to a shoulder injury. I haven't filled my prescription and I haven't taken them for 3 days. I'm experiencing intense aching everywhere in my body, loss of appetite, sneezing, runny nose, nausea, shaking, loss of sleep, and mood swings. Is it possible that i'm experiencing withdrawal after taking this medication for almost a month solid? I wasn't sure if you can go through withdrawal after only a month. Please help?
