Hi Sarajara...
One of my aunt has the same problem as your husband.
And she too went through a lot of pain.
I am not sure if it can get alright permanently,and will therefore not give you any false hopes...
But have you heard of
"Arya Vaidya Shala" in
Cochin, Kerala?? They do have a solution for this....
The treatment is completely natural i.e
ayurvedic and effective...
Do give it a try because my aunt was treated there and her condition is much better now, infact really good.!!
Dont be upset...just go for it,...and everything will be ok...
Regards...
