Amibid LA and expectation

Dec. 02 was issued by RX Amibid DM 30-600Cr Qty 60 Two twice per day,acct heavy lung congestion. Ater condition cleared did not refill Rx in expectation of reoccurance in future. As during course of usage noticed an effect of alleviationc of PN intoes and fingers. Thinking it"s just a fluke or way of PN, until this May during another heavy chest congestion Hay Fever_ Asthma and another ongoing round of Amibid DM, the PN has abated again. AQm wonering if this could be an alternatine means of treating Pn other than Neurontin?? Any Dr. or Pharn care to respond for or agaqinst? Thanks
