In most cases, your doctor will be the one who diagnoses your condition initially.
In my case, this was a doctor who I trusted in the country where I was living and working, the reason I went to see him was that I had swelling in my feet, legs and hands.
His initial examination indicated Rheumatiod Arthritis, which was subsequently confirmed from a blood test and he advised that I take pain killers for the pain and anti-inflamatory drugs to reduce the swelling.
This did help for some time but the swelling came back frequently, this was when I realized I had a problem and started considering my future and discussing this with my lady friend of 8 years.
We decided that moving back home was the right thing to do for a variety of reasons.
Once returning, I consulted with another doctor in order begin receiving longer term treatment which consisted of Diclofenic Sodium for the swelling and Co-Codomol for the pain.
I would most definitely recommend that a health professional is consulted before taking either in order to get the correct dosage and to make sure that they are suitable for you.
Keep Positive 🙂
