Ooh that long cold pack sounds heavenly. I finally gave in and bought a Headache Hat, but I've amassed a big collection of smaller ones so I never have to wait for one to freeze. That long one sounds like it would be a nice addition.
I hope what was learned helps hurry a solution. I have had progressively worse positional headaches for 13 years without a solution so can give you some of my strategies to manage. Caffiene and a gram pill of salt in the morning helps some, and abdominal binder helps, and if laying down isn't helping or quick enough, I have an inversion table that can stop the sagging pain pretty fast. Hoping you find a permanent solution quickly but maybe some of that can help in the meantime.
I would avoid bending, lifting and twisting (BLTs) until you get this figured out. Buy a grabber tool. Ask for help with carrying things.
Yes, that's no problem. You're still evening out the pressure between your head and butt by lying down, whatever the position. They're most concerned with big, sudden spikes in intracranial pressure (ICP), so as long as you're not doing seriously bendy yoga-like positions in your sleep, then lying however you're used or however is comfortable for you is usually just fine.
Be sure to never hold in a sneeze! Let it gooooo! (Keep your mouth open during a sneeze.) And no straining on the toilet. (One of the experts tells all of his patients to start taking Miralax three days before their procedures.) Do NOT lift anything heavier than a gallon of milk. Bending over to pick up something from, or to put something down on the floor is bad. (Consider getting one of these.) Of course if you have small children or a small pet, sometimes you might not have a choice, but otherwise just don't do the thing. Don't let anyone give you a bear hug. (Sadly I think the pandemic is helping with that.) If you get a cough, try to treat it aggressively with meds, but sometimes there's just no stopping it. These are all things I've seen people say caused them to re-leak. Also avoid walking on soft ground like at sandy beaches. (This one stumped me, but I guess doing so uses enough of our core to raise ICP in bursts.) The hardest one for me has been to not do a huge strrrrrrrrretch when I'm waking up. It involves a big Valsalva maneuver, which is totally off limits, but I couldn't help it! I just do it before I'm even fully awake. I think I've finally broken that habit now though.
I am down to maybe a good hour a day. Then if I can make myself lie flat for a couple of hours I might get 30-40 min with a good brain/no pain. An abdominal belt and 1gram of salt in the morning can extend this maybe 40% or so.
Best of luck!
I use Keep on Android! I've tried symptom trackers but never found one that was as good as my just logging things in Keep.
The best tracker app I could find at the time was actually Period Tracker which allowed me to add symptoms and pick icons for each so I just tapped those icons when I had those symptoms. But that was several years ago. I'm sure there must be better apps or there by now.
