Is Flying Safe After Sever Headache And Pressure In Head?

I was recently diagnosed with a low pressure headache and was admitted as an emergency as the pain was so severe. I was given an epidural blood patch which seems to have solved the problem. I have been left with a constant ringing and thumping in my head for which I am taking medication. I am supposed to be going to a wedding in Ireland next week and was just wondering whether I am able to fly or not. I was discharged from hospital 2 weeks on Monday.
