Are severe headaches a possible reaction to low-dose aspirin in people with MPNs?

It's concerning that you're experiencing such intense headaches after starting aspirin. While low-dose aspirin is commonly used to help with microvascular symptoms in MPNs, headaches can occur for several reasons in your situation.

Headaches in MPNs can be caused by:
- Thickened blood from elevated blood cell counts
- Active disease within small blood vessels
- Side effects from treatments
- Bone pain in the skull from abnormal blood cell production

Your blood counts show elevated hemoglobin (15.2) and hematocrit (46%), which can contribute to blood thickening and pressure-like headaches. The fact that your headache pattern changed dramatically after starting aspirin and improved when you stopped suggests a possible connection.

Some people with MPNs do find relief from microvascular symptoms like headaches with low-dose aspirin, but individual responses vary. The localized, excruciating pain you're describing is definitely something your doctor needs to evaluate.

It's good that you're seeing your doctor in 3 days. They may want to assess whether your symptoms are related to the aspirin itself, your underlying MPN activity, or if alternative treatments might work better for you. Your enlarged spleen (17.9cm) also indicates active disease that needs monitoring.
