The aim of the study was to compare botulinum toxin type a verses conventional oral treatment as a second line treatment of painful diabetic peripheral neuropathy. This study was conducted as a comparative study on 30 patients with type 2 diabetes mellitus proved by nerve conduction study on carbamazepine. Patients were divided randomly into 3 groups. First group was add on duloxetine, second was add on gabapentin and the third group was injected intradermal with botulinum toxin A.
