Anybody else has multiple sclerosis? What are your symptoms?

my friend has that disease. it sucks quite a bit. he has been suffering for over 15 years. recently he got major attack wherein his both legs got numb and he lost vision of one of his eyes. he was admitted to hospital and eventually these extreme symptoms subsided. that happens when you get an attack. generally person's walking, balance, gait, speech, writing and other motor activities get affected which keeps deteriorating with time. what happens in this disease is body's own immune system eats up myelin sheath of nerve cells and exposing the nerve which causes severe tingling sensation and occasional numbness. worst part is there is no cure for this. doctors say that only a healthy lifestyle can help to keep symptoms under check.
