Hello I'm a 17 year old male, I've been having a warm feeling in my lower left leg, mostly in my left foot. I've also had this feeling on my upper left chest as well as in my ears, it feels like that part of my body is being soaked in warm water, my doctor didn't pay much attention to this and was clueless. I'm kind of freaked out at the moment seeing this has been going on for weeks and feels very unnatural, could a blood clot cause this? and any ideas? Meds I'm taking Singular (For help sleeping at night due to shortness of breath), Advair (For breathing issues), Bactrim (For possible infection), Zyrtec, Nasonex. This has been going on for 2 weeks that's about the time I started taking Singular if I remember correctly.
