Anyone who is steroid-dependent can experience a rapid deterioration in their health if they encounter a gastric infection, especially where this involves a fever. Addison's disease or a pituitary condition, CAH and other forms of adrenal insufficiency are all vulnerable to adrenal crisis in these circumstances. If you or a loved one are steroid-dependent and not absorbing or keeping oral medication down, you need injected steroids rapidly. Knowing how and when to give an emergency intramuscular hydrocortisone injection can save the life of someone with Addison's disease or other forms of steroid-dependence.
A couple thoughts, and let me start by saying I am fairly new to spine issues. I have an L5-S1 large bulging disc pressing on the right Sciatic Nerve. Significant pain for one month. Probably not the person to give advice (some posters have earned a PhD in pain not by choice) but reading your post made me want to offer what I have found. I hope you find an answer, you deserve it. 1. Medical advice needs to come from multiple sources so if you have yet to seek alternative opinions probably best to do that now. 2. I personally believe the cycle of pain requires an element of finding your means to break it. I found the best, all be it hard thing to do was to push myself out for a walk and also to go to work. I believe there is a tough balance with this that requires hearing the medical advice to know when to not push it but also knowing if you don't push a bit then the pain owns us. 3. At 7 months, I can't help but think the conservative approach isn't working and you should be talking to a surgeon. Again, I hope you find an answer.
