Hi. I have had steroid injection in my knees this week and so my warfarin was stopped 4 days before and then told to take double normal dose for 2 days afterwards. I normally take 4mg so up to 8mg now. I have been having my injections for about 10 years with no side effects. Last night I took the first dose of 8mg and have since had a horrendous Headache does anyone know if this would be due to the higher dose or just bad luck on my part. I do not suffer from migraine or headaches normally.
Any advice would be helpful. Many thanks
