Brief Summary
This phase II trial tests whether PEA works to relieve the symptoms of chemotherapy-induced peripheral neuropathy in patients with cancer. Chemotherapy-induced peripheral neuropathy refers to a nerve problem that causes pain, numbness, tingling, or muscle weakness in different parts of the body, and is caused by chemotherapy. PEA may be useful against bothersome nerve symptoms.

Outcome Measures
Primary Outcomes (1)
Mean Change in Quality of Life Questionnaire - Chemotherapy-Induced Peripheral Neuropathy 20 (CIPN20) Score
Will be scored and summarized at each time point for each patient. The change from baseline to 8 weeks will then be calculated for each patient. The mean, standard deviation, and median (range) of the change will be calculated for each PEA arm and the combined placebo arm. The difference in change scores between each PEA arm and the combined placebo will be estimated along with a 95% confidence interval. For the primary analysis, the CIPN20 analysis dataset will include all eligible patients who are randomized, initiated treatment, and completed the baseline questionnaire. For patients who go off protocol treatment before 8 weeks, the score at their final observation will be used to calculate the change. The CIPN20 includes 20 items, each asking a participant to rate their experience with certain symptoms from 1 to 4, with 1 being no difficulty with the symptom and 4 being the most difficulty with the symptom. Answers are then summed to give a total score from 20 to 80.

- Patient must note tingling, numbness or pain symptoms of at least a four out of ten =\< 7 days prior to registration.
- Note: On a 0-10 scale where zero was 'no problem' and ten being 'as bad a problem that could be imagined': how much of a problem has numbness, tingling, and/or pain in your fingers and/or toes been in the past week?
- Patient must be able to speak, read and comprehend English

- +11 more criteria
You may not qualify if:

- Previous history of peripheral neuropathy prior to receiving neurotoxic chemotherapy
- Neuropathy from human immunodeficiency virus (HIV) infection. Note: Patients with HIV infections are eligible as long as they do not have a neuropathy from their viral illness
- Concurrent use of a cannabis product (tetrahydrocannabinol \[THC\] and/or cannabidiol \[CBD\]). Patients should have discontinued these products \>= 4 weeks prior to registration
- Current or previous use of PEA
- Currently receiving or planning to start any of the following agents: opioids, duloxetine, gabapentin or pregabalin. Patients are eligible if they discontinue these medications \>= 1 week prior to registration
