Nerves stuck and pulling. Help me.

I am taking Ayurvedic memory booster supplement such as medhyarasayan, brahmi and Shilajit. They all are working well and I am happy with effects. I had chronic stress six years ago and I am taking these since those times. My brain now stucks somewhere with these and it pressures my body organs such that liver responds with yellowing my eyes. My brain also becomes heated. If I put ice there or pull foreskin towards nose, these nerves get calmer and I can feel that stuck gone. I get clearer breath and feel more controlled. This heat also cause iron to get removed from my body. I don't know what's stuck that is cured if I pull foreskin ahead. Please help because I don't know why this is happening. And no doctor takes this as a problem. I cannot earn or work. Please help me.
