Here good news is there is complete treatment treatment available for leprosy and you just need to talk to your doctor. Usual way of taking treatment is as below: Dapsone, which is bacteriostatic or weakly bactericidal against M. leprae, was the mainstay treatment for leprosy for many years until widespread resistant strains appeared. Combination therapy has become essential to slow or prevent the development of resistance. Rifampicin is now combined with dapsone to treat paucibacillary leprosy. Rifampicin and clofazimine are now combined with dapsone to treat multibacillary leprosy. Now for nerve pain generally specific treatment is not there but you can take nerve block injection to reduce pain as well do regular physiotherapy to improve the functional ability along with muscle girth. It will also help to give you some more pain relief. Once you get over with your problem of leprosy I suggest to have good enough omega 3 suppliment on a regular basis. Because this omega 3 is a insulation material for nerves which will help you to recover even better and early. Further I suggest to talk to your doctor for detail discussion. You may take secondary opinion from another well known doctor too if needed. Here I have given you general guideline but specific suggestion can be given only after complite check up and examination only. How ever I still suggest to follow the steps I have suggested and I am sure this will be helpful for you. Take care.
