My hands and arms have been having a burning sensation on the top of them. It feels like a sunburn, but I m not sunburned. After I ve been outside, they feel hot to the touch too. Hot water almost burns me. It s a weird feeling. Sometimes it feels like water is hitting my arms too, when it s not raining. Could it be a side effect to something? I was recently on Doxycycline Hyclate (took it for two weeks, finished yesterday), but I didn t see this on the side effects list.
