Follow your doctor's instructions, but I was told no exercise. Drink lots of water & caffeine, if that helps. Whenever you have a chance, lie down. If the epidural was in your low back, probably the most comfortable position will be curled up on your side. Otherwise, you can put several pillows under your legs & sleep on your back. As it was explained to me, the more you move, the more stress it puts on the wound & the less likely it is to heal.
I really don't get what the deal with your doctors is. They should consider this urgent & get you in right away. There are people who have developed serious complications from dural punctures & typically doctors who cause them want to take care of it asap. It is rare to develop any serious problems, but really, why risk it at all when the solution is so simple. Sometimes the puncture does heal on its own, but I think it's like almost half of people who get them need a blood patch to recover. Like I said, it really should be the doctor who did the dural puncture who treats you with the blood patch. You have a much higher chance of him finding the right place the first time than if you get a different doctor to do it. If need be, it can even be done in an ER (though that would be my last choice). I just think it's extremely cruel that they know what the problem is, what the cause is, where the problem is located & what needs to be done to treat it, yet they are telling you to wait.
Blood patches are very, very simple procedures. It only takes maybe 10 minutes top to complete. All they do is take a very sterile needle & draw blood from your arm (like for a CBC, but with extra sterility precautions). Then, they take it & attach it to a long, thin needle & inject it into your back. They might massage it for a few seconds. Then you lie down for 30-60 minutes (my doc lets me lie in the dark, which helps me out). Someone else should drive you home & you rest flat on your back in the dark for the remainder of the day -- after a couple days, you can go back to your normal activities, including working out. If possible, it would be ideal to do it under flouroscopy to make sure they get the right place, but that's not necessary. Either way, I think you need to really push your doctors to treat you sooner rather than later. I would be hopping mad & threatening to sue (& I don't say that lightly) if they gave me the run around like they've given you.
