Hi Mark,
Welcome on the forum,i am also a thal minor,tiredness and headaches are the most common symptoms among thal minors,heamoglobin being the carrier of oxygen in the body,if heamoglobin is low,you'll not get enough oxygen and get easily tired.Have you ever checked your HB levels?
Taking supplements can give you a dramatic change,though it won't be overnight change,but you'll definitely feel a positive difference in your energy levels.All thals,wether minor or major are advised to take folic acid daily,in your case wheat grass might help,my daughter is a transfusion dependent intermedia and i felt a definite upward change in her energy levels when i started giving her wheat grass.You can buy it online from
www.drwheatgrass.com .it comes in the form of super shots.
Another natural product members of our forum have tried recently is carao fruit syrup,it has helped my daughter maintaining her hb for 4 weeks.it is said that it has showed very positive results in thal minors.You can read more about it here

I am sorry i don't know much about your knee problem,Let's wait for Andy to comment about it,also are you taking calcium and vitamin D? It is a must for bone health.
I hope you know that if two thal minors are partners and they opt to start a family ,there is 25% chance in every pregnancy that they can have a thal major baby,how old are your sons,inform them about this when they grow up,so that one day when they want to start a family they can get their partners checked for thal trait.I hope this helps.
take care,
Zaini.
