Peripheral neuropathy

Hi @Ebony2102, From the drug literature I gather it can take some days to two weeks or so for Gabapentin to reach therapeutic levels and longer before it is fulling working. (see britishpainsociety.com - gabapentin)
Speaking with the doctor who prescribed gabapentin to you could help to confirm this information.
In terms of other options to help in the meantime, I note capsaicin cream can be used on the painful areas. But be aware that the cream causes a burning sensation which can be uncomfortable if it comes in contact with sensitive skin such as eyelids or mucous tissue such as mouth etc. ref Mayo Clinic - Peripheral Neuropathy.
And small doses of anti-depressant medication may also help but may take just as long as Gabapentin to work. (ref. Mayo Clinic - Peripheral Neuropathy).
Best Wishes.

I agree with @kitedoc but would add that if you try the capsaicin cream and you use a finger prick glucometer then it would be wise to wear gloves when applying the cream, it really lingers on the hands afterwards.
