Thanks Ark, Laura the Château for this session very informative indeed!!!...  
 
 
I hope that Laura get rid of that illness very soon, one observation that I have to say about it
is that at the start of last year (2014) I have some initial symptoms of arthritis, I immediately started 
using a more higher dose of Omega 3 pills in just 10 day my symptoms vanished...
Omega-3:
    Reduces joint tenderness
    Reduces morning stiffness
    Reduces the amount of painkillers needed
    Reduces enzymes that destroy cartilage
    Increases grip strength
    Enhances walking pace
There are two main types of arthritis. Rheumatoid arthritis (RA) and osteoarthritis (OA) can
cause aches and discomfort in your joints and make it difficult to enjoy life the way you used to.

The Omega3 that I used was the one of 1200Mg  having the following composition:
EPA = 247mg      DHA = 115mg
it is advised that people with more than 60 years take doses of Omega 3 with EPA less than 200mg 
(Why? this is what I found)...
Here is how much Omega-3 you need per day:
    For depression, you need: 1000 mg per day
    For heart disease, you need: 1000 mg per day
    For skin disorders, you need: 1000 mg per day
    For blood pressure, you need: 2000 mg per day
    
For arthritis, you need: 2000 mg per day
    For asthma, you need: 2000 mg per day
    For diabetes, you need: 2000 mg per day
    For high triglycerides, you need: 3000 mg per day

and for people with less than 60 years old or more younger the EPA doses have to be more than 200mg
(When in normal conditions - just for health manutention...)
So a little bit of initial caution on that EPA amount. 
One important note about the Omega3 that is sold is that it is very difficult to find pills with more than
200mg of EPA in just one capsule (usually that amount is for two or more capsules.) 
TIP: Some product labels try to fool you by saying 1000 mg Omega-3 per serving…
but if you read the back, you’ll find that a serving is 3 pills. You need 1000 mg in JUST ONE PILL.
That way, you just need one pill a day.
I recommend 
The label brand:  Fish Oil from Natures Bounty Inc. _http://www.naturesbounty.com/
I hope that you succeed and be well Laura...  cheers!!!...
