I Am Using ELavil For Neuropathy Pain, Which Is Giving

i am using ELavil for neuropathy pain, which is giving me moderate relief but not great. Lyrica worked better for me but after i had been on it for several month i had a lot of tingling in lips and tongue that got worse. Am wondering if i can take a small amount of both the elavil and the lyrica in combination for the neuropathy i have?
