I experienced a lot of head pressure and similar sensations (you can read details in my website below). Ibuprofen is a good start (my doc said I could take up to 800 mg, 3x per day -- which means 4 tablets after each meal). It does help, but the symptoms probably will hang around for at least a few weeks or perhaps months. My experience during the course of the first year was very up and down, with symptoms coming and going. Things really settled down in month 13.
The temptation to take steroids is significant. I took two rounds of decadron in months 4 and 6 after treatment, when I just wanted some relief from the symptoms, whcih for me were pretty intense. They are very unpleasant and hard on the body. Of course, having taking them myself, I do understand the desire for relief. I read all the horrible things about steroids and took them anyway. But having done so, I can say that they truly are harsh drugs that are best avoided if possible. If you decide to take them, ask your doctor to prescribe the lowest dose possible.
Best,
Francesco
