<s>[INST] I ve take Norco 10/325 mg for long but then sudden I had bad hips. With Norco does not helps and I had new prescribed called Tramadol 50 mg. Norco helps my pain go away fast for pain neck and migraine, but I am not sure about Tramadol for my hip with small arthritis/tendonitis. Should I take one pill of Tramadol and the other half of Norco? It is safe or not? [/INST] Here you need to know that tramadol is also a good painkiller, as per you hip, neck and any other body part if there is pain first you need to know why it is paining? What is the basic cause of this pain? Until and unless you Don't treat the basic cause of pain it will not help you so much taking painkiller all the time. So get your pain evaluated with x-ray or scan of respected body part and checked it with orthopedic doctor. You can also check your complete blood count as well calcium and vitamin D test to know there should not be anything wrong here. For your question on Chat Doctor.  Let me tell you, your doctor must have given you medication after evaluating your condition properly and do not change  </s>
