The excessive sweating could be because of hormonal problem like hypothyroidism. It can also be present sometimes without any internal disease in which case the treatment is to be continued for a long time. There are certain lotions and tablets which can offer temporary relief but regular treatment would be needed. Also you can consider taking Botox injection into your palms and soles which would have to be taken once in six to eight months and you wouldn't have to worry about continuous treatment on a daily basis. I have personally used Botox for this purpose in many patients and all have been pretty satisfied with the response. You can come and visit me for an evaluation so we can decide on the next date that would suit you best. Hope this is helpful.
