I am 56, male. A pale skin on the forearm at the age of 16 diagnosed as Hensen's. I took Dapson mono-therapy for 6 months. Paleness disappeared but loss of sensation spread from wrist to elbow in next 30 years. At age 46, I felt pain at ulnar nerve at right elbow. Took Dapson multi therapy for 5 months. When symptoms of peripheral neuropathy appeared at feet, drugs discontinued. For the last 10 years, controlling neuropathy with Gabantin 100 1-0-1 and Nexito Plus 0-0-1. Recently, had joint pains at fingers and shoulders and taking Etostal-90, Pantonix-40 and Methylcobalamine 1500 mcg. Nose is getting dried. Should I stop any medicines? How long should I continue with Gabantin and Nexito Plus?
