I am 8 months post Clipping of my aneurysm and yes, I suffer with daily headaches. Some manageable with meds others just won't go away. I generally wake up with a 'Hangover' type head. I can also at times feel a little sick but not to the point of vomiting. I take daily medication usually 3 times a day... Paracetomol/Codeine tablets. I have been trying to cut back on the codeine tablets to avoid the 'rebound' affect and take straight paracetemol but I'm not sure this is helping mu headaches. My headaches have seem to become worse over the last month. I had a CT at 4 months to check if everything was okay and it was. Everything I read and am told is that headaches are common!
I also suffer from neck pain... it doesnt feel muscular but vascular...if that's a good way to put it. This neck pain and add to my headache or bring it on. It can go away as quick as it came. When I have my headaches, I have a great awareness of where I was operated on...my head gets itchy and the numbness returns.
I had a Neuro Checkup at 3 months with specialist team but don't have another until November 2016. I think I need a check up with them sooner to discuss headaches. I live in Australia, so our system might be different regarding checkups. I see my local GP usually every month for work requirements.
For you, 4 1/2 years is a long time to deal with headaches! I hope you find some relief.
I tend to find that diet can be a trigger! Both good and bad. My head feels better, for some reason when I eat. This i need to discuss with specialist.
All the best.
