Hi @jalexy12, I wish you all the luck with the venogram/angiogram on Wednesday! Thank you also for listing your symptoms, they seem to align really well with what I have been experiencing. One other potentially relevant thing I forgot to add in my other post last week about my venogram experience with Dr Mehta is that I also made sure to discuss with him at length immediately before the procedure what head positions are worst for me in terms of symptoms, and how to best recreate them during the venogram. In a similar fashion to what you report, my head and cervical pressure symptoms are worse when seated or walking. My theory for this is that when my back neck muscles contract to keep my head up, they compress the collateral veins at the back of my head, which seem to be one of my main venous drainage routes. Given this, Dr Mehta and I worked together in the first part of the venogram, after I was laid on the table, to identify the “worst” head position we could achieve. This involved using a 30° wedge under my neck, and me pressing my neck slightly in the wedge to compress the vasculature at the back of my head, which recreated reasonably well the sensations I get during my day-to-day life. Indeed, when he took the wedge away and allowed my head to rest naturally on the table, the pressure gradient dropped significantly. Maybe worth discussing with him about your specifics.
