Can Crystal Meth Overdose Cause Rashes On Throat?

Now I ve never done this before but I made the stupid decision to give into peer pressure while clearly thinking with the wrong head. I didn t know much at all about this drug and ended up using it all night into the morning and then returned home.. Things seemed fine. Just thought I was hungover when I was puking And feeling shitty but the next morning I woke up sweating profusely, hot to the touch but no fever vomiting, shorteness of breath, heart palpitations .. Deleriois, and Uncontrolable movements full time. I got concerned and went to the hospital and told them what happened and they basically treated me like a street person and gave me little help of information and checked my heart and blood and then released me .. That was Monday. The same problems persisted yesterday so I went and seen a doctor and got the same results.. Now I m just curious if I m actually okay and just wAiting out the effects of the drug or if I should still be seeking help? Reason being is I am exhibiting many of the side effects that go along with a crystal meth overdose and after learning how serious this shit actually is I m quite concerned for my health,.they did tell me I m quite dehydrated so I ve been working on that. I m still sweating and feeling hot but with a regular body temperature..I m fatigued , dried up from dehydration and twitchy.. I ve stopped vommiting yesterday and no longer have a shortness of breath or heart palpitations. Funny little pains coming from my organs and still confused but I ve developed an unexplainable rash on my throat.. Can you please steer me in the right direction ? Help me!
