I was just wondering if i would be eligible for sickness allowance?

I have GORD as well as stomach ulcers which means most nights i am awake for hours with horrendous pain in my chest/back and can stay with me all day. I've already had to call in sick twice at work. Its not even that but when i am in the middle of work i get it and have to sit down or go home.

I had thought about taking time off work but we really cannot afford it and it looks like ill be waiting well over 6 months to see a specialist.

I've read that i just need to get a medical certificate from my doctor to claim but is my condition 'bad' enough to be eligible for the payment? Will i be required to see a doctor that they reccommend.

Any info is muchly appreciated.
