Ichthyosis. But result still the same.

Hi I am having cracked skin or flaky skin which looks like snake or fish body. My leg and hand are majorly affected by this. Skin will become normal in summer when I sweat more. But in winter days its like hell. Even I do exercise then I produce less sweat. Due to this I feel embarrassing and I cant wear half sleeves shirt and half pants. Every time I used to think about it and why this happened to me. Family History: I believe my mom had same thing but in very less extent but now her skin is normal. I am having one brother and four sisters but no one having the skin like me. I am the one who has affected by this dieses. Please suggest what I have to do. Already I have taken homeopathy medicine from Dr Batra which was costly for more than one year but result still the same.
