My legs have increasing become more and more sensitive to heat over the last 4 years.It was very slow and insidious when the heat sensitivity first started and at first I thought I must be seeing things but it has progressively gotten worse. I have to be very careful how hot the shower or bath is as I get quite a heat rash and it makes my adductor muscles spasm, ouchie. Over the last year my arms occasionally due it in the shower and it actually runs along nerves on both my legs and arms. You could easily do neuroanatomy on me. I will be starting the 10 day outpatient Ketamine treatment protocol the middle of Dec. I hope it will help with the heat sensitivity.
