I have anemia, high rdw, low hemoglobin and hematocrit, low mchc, slightly elevated platelets, and small red spots popping up on skin along with abdominal pain, lymph node swelling, & abnormally heavy menstruation. what could be wrong?

Your question requires more details to answer. This forum is not designed for personal health concerns. See your doctor. You have several different things that require careful attention. In general, you may have anemia, considering that I cannot see the entire lab work, although low hemoglobin can be from too much fluid in the body As you can see, more details are needed.

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, it would have helped had you provided the actual results, high or low are sufficient information. Wish you good health!
