instruction: hello doctor I have multiple questions recently I might have been exposed to mercury vapor in a hotel room I was sleeping in for around 10 hours the room was small and the type of mercury was unknown I remember the one type of chemical was clear liquid watery substance and the other once was more clay grey with dissolved in water I left the room around 10 hours later and did not touch anything but I might have breathed in the vapors in this small room I also washed away the crystals that has landed on the carpet all of these substances I have no clue about what was except when I asked I was told mercury 5 months later I got a pins and needles feeling in arms and feet with has lasted a month but no other symptoms until now I feel like I have some kind of internal vibration in my feet and my knees are shaking when I stand up like I am freezing or have done a hard workout from time to time I went to the doctor in my area and told him about what had happened and showed him pictures of the various substances and I took a urine test and a blood test and this was made around 130 days after possible initial exposure and the test came back at normal levels but can it be that I had a toxic exposure and the mercury has already settled in organs and therefore do not show in blood or urine I am not sure about the half life times in these metals or can I settle down and accept the test results are final and that mercury levels do indeed declear that I have not had an exposure of toxic levels and that my symptoms might be of other cause if not number one is the cause then a few months before that I got an acute pins and needles feeling in hands and feet paresthesia which continued until today and it increased over the one month before it stabilized a little it went from pins and burning sensations different parts of the hands and pins feeling in the legs a few times I got shooting pain from a finger and up my arm but very rarely which has not returned after alcohol consumption one weekend it went from stabilized to worse and I also noticed my knees shakes a little when I stand still but not when I am walking the feeling can be compared to when you are freezing or after a hard workout on your feet it started with a sensation under my feet like I was standing on a vibrating phone and then moved up to my calves which felt like they were bubbling inside and now my knees which shake when I stand but the vibration under the feet is gone my hands also one week felt like they was shocked and they turned red and stiff the kind of feel like I put my hands down in hot water and then removed them red spots on my hands underneath the skin appeared and the closest thing I found resembling it was pura when I looked up causes online my hands are much better now but it still feels like some areas are sunburnt and my fingertips are peeling but I think that is because of winter and dry weather the red spots remains I have taken multiple blood test for vitamins deficiency and other things which turned out normal besides vitamin which was a little to low and neurological test like standing on one foot with eyes closed and finger pointing and sensation test of sharp cold hot which all was normal I am taking a mri next month to check for is and other conditions sorry for making this text so unclear and poorly written but I have no idea of what this might be so doctor do you have any ideas about what this can be
output: hello I read carefully your question and would explain that your symptoms are not typical of mercury intoxication anyway I would recommend performing nerve conduction to in order to examine your nerves and a brain mri in order to examine your brain as the neurological exam is normal I do not think it the brain mri will result abnormal a cervical spine mri may be necessary too in order to exclude possible spinal cord compression in this region due to a bulging disc
