The MCV and MCH are both slightly low, so it could be thal minor. The ESR is very high. Have you been given any explanation for that? I think DNA testing should be done to find out if it's alpha or beta thal and if it's beta trait, what is the mutation? The spleen and liver are both enlarged, due to hemolysis, but why beyond what is normally seen with thal trait? Is this totally due to thal or is something else involved? DNA testing will help answer this.
The pale skin is due to less oxygen reaching the extremities. I would suggest natural vitamin E, 100-200 IU daily, as this helps the ciruclation. Exercise will also help, but the problem is that the irregular shaped red blood cells do not pass through the smallest blood vessels easily.
