I am taking tramadol and gabapentin for a bulging disc and neuropathy. I am noticing I have a persistent hoarsenes in my throat is this anything to be concerned about and could it be related to my medication

Hoarseness. It's possible the change in your voice is related to the medication. Normally these medicines do not cause this however. Perhaps it is more likely to be unrelated. It is not related to the bulging disc problem. The only concern perhaps is if it is an unrelated issue. If you are a smoker, and it is a few weeks old, it may be worth checking on.
I . I have been prescribing both medications for many years and have not seen this problem. Consult your pharmacists as they get regular updates of medications and can give you a more definitive answer.
