I have been on methotrexate for 8 years 12.5 mg per week. The last couple of weeks I have had a very strange thing happen. About 5 hours after taking may medication, I have these very quick shock-like sensations over my whole head…some are more intense than others, maybe 10 total within 30 minutes, each only lasting a second. What could this be?
Likely not methotrexate and frankly, I don’t know what you have.
