<s>[INST] Hi Dr.I was diagnosed with aplastic amnemia 7 years ago. I am currently on my lowest dose of cyclosporin 25mg. My platlet count today was 51 so my Dr doubled my dose again to 50mg.  I would like to know why I have burning headache. And this then makes me nauscious? please help!! [/INST] Hi, Thanks for asking. Based on your clinical history and query, my opinion is as follows:1. Severe headache is possibly due to anemia and hence reduced oxygenation causing weakness, dizziness and hence a feel of headache.2. Medication and reduced WBC count possibly resulting in infection of GI tract could be making you nauseous.3. Continue the therapy and try to improve the various blood counts. Hope it helps. Any further queries, happy to help again. </s>
