I recently started gabapentin for anxiety and i noticed pitting edema on my right foot and ankle and shortness of breath. side effect or panic attack?

Neither: Unilateral edema is not due to any drug (which effects both feet equally). Same for panic. Unilateral edema is due a blood clot until proven otherwise. If you happen to use oral contraceptives, your risk is much increased. Your shortness of breath is ominous - you need prompt evaluation.

Gabapentin: Hi, lower extremity swelling could be a side effect of Gabapentin but I don't believe your Shortness of Breath is due to Gabapentin, I suggest that you contact ur prescribing doctor to change your medication. Best of luck.

I don't think a: Panic attack would cause pitting edema....it may well be a side effect. I would imagine stopping the medication would help you find out but speak to the doctor before doing anything and express your concern.....also try and relax so you don't have panic attack, if your having difficulty breathing then go to the ER.
