My husband had terrible problems with anemia including low platelets at times, low iron, other low blood test results and hemolytic anemia. He was under the care of a hematologist. He was prescribed a high dose Folic acid, took iron pills daily, and I gave him ProCrit injections three times per week. Even with all of that, his blood would still bump along at the bottom of the range and he had many, many transfusions, and some iron IVs. It was a tough problem for him.
Well into the situation, it was discovered that he had a problem in the lining of his stomach, causing seepage of blood and had an argon vapor cauterization on about 1/3 of it. He also had kidney problems which contributed.
I hope you are under the care of a hematologist. Blood problems can make you very, very tired because they leave you short of oxygen, and low platelets can cause bleeding areas under the skin. Joe had those spots on his hands when his platelets were low.
Your doctors and you are going to have to stay on top of the bloodwork. I wish you well.
