My father is having khasna issue. It's that bad that he even can not sleep. Its so painful to see him in such situation. He tried lots of medicine's including home remedies. As per my observation this issues happens once a year to him. The medicine what worked for him will not work for him next year. He use to spent whole night siting only. As he lies down issue starts. He was treated for non hochkin cancer 2 years back. He was diagnosed as diabetic patient. He is non alcoholic non smoker. Due to all these medical issues he is going under depression. Please help me to get rid of this issue ASAP. Thanks in advance.
