After 10 years sober I relapsed 48 hours ago. I used used meth and had a severe reaction. I nursed myself for about 24 hrs til until I became short of breath. My face, neck , and chest became fire red, swollen, and distorted. I had numbing of my limbs, edema in feet and legs, and what appeared to be white pools or clumps under my skin on my face. Then, I could not catch my breath. I went to the ER where oxygen, benadryl, and prednisone were administered. I now have a deep regret , a rx for prednisone, and white clumps on my face under my skin for my reward. I would like to know what the clumps are, will they go away, and how do I have this treated (home care)?
