If this continues please visit an urgent care facility or the ER. It is unusual to experience such an extreme reaction to the morphine. Also, unless medical professionals are able to get it under control, get back on the methadone. This isn’t worth some serious health complication.
It generally takes about 30 minutes for DPH to kick in. If you aren’t feeling relief from 25mg, try taking another 25-50mg. If 25mg makes you feel worse, do not take more and get yourself to a doctor who can check it out. Urgent care centers are probably wholly unable to deal with this issue as it requires a very specific specialization they probably won’t have, so although it is more expensive and ER may be a better bet (although by the same token they may have no clue).
Can you monitor your BP with an analytical device? Like a BP meter or whatever? As opposed to just guessing what it is. That can actually cause a panic attack, which will increase you BP/discomfort in itself. If you can monitor it, let us know what it is versus what it normally is. If you have BP medication, it is probably a good idea to take it. Just check to see if it has any interactions with morphine or DPH (or with us) first.
I’m sorry to hear you are going through this Barbie. Sounds really horrible and very scary. This is unlikely to actually cause you real harm, but it is unsettling enough that you should really get a medical professional to check up on what you’re experiencing.
And just to reiterate, it still sounds like you’re experiencing a histamine reaction. Try laying down with the lights off in a cool room. That may help. Anything you can do to relax with something that doesn’t stimulate you any more than you already are (so watching TV or playing games isn’t the best idea).
Unless you begin to have trouble breathing, histamines reactions, while very unpleasant, are generally not very dangerous. If you begin to find your face, for instance, is become swollen and inflamed or begin to have trouble breathing, that is the sign you need to get to an ER ASAP. But short of difficulty breathing, it shouldn’t actually be dangerous.
I now see it is more than 30 minutes since taking DPH. How are you feeling?
