For about the past six to seven months, I have been experiencing what feels like hot flashes. The affected area has been mainly the back of my neck and down to my upper back. My skin feels hot, but sometimes I also get chills or start sweating. I do not know if there are any physical issues, but it feels really uncomfortable.
Usually when this happens, I try and take some vital measurements to see if my blood pressure or blood sugar is either too low or too high. However, I have not found any correlation to either of those two factors. On the Mayo Clinic site linked above, they said the primary cause of hot flashes is menopause. Obviously, that is not the cause for me so it is likely a side effect of the many drugs I take.
Just now, I woke up to use the bathroom. I measured my blood sugar and it was a bit high at 190, likely from eating too much rice for dinner. I was feeling fine, i.e., no burning skin sensation. My insulin app said to inject four units of Humalog, and after a few minutes, the burning sensation appeared on my back. I shoot Humalog several times daily. Is that the cause?
Even now, after twenty minutes and only four units, my back is still burning, and I feel a bit out of breath. I looked online and found some conflicting information. Some sites said Humalog can cause chills and sweating, but the official website listed sweating as a secondary side effect of hypoglycemia. Here is what is listed as common side effects:

And here are severe allergic reactions:

I have been taking Humalog since my kidney transplant three years ago, and I do not believe I have had any allergic reactions to it. I typically shoot both Toujeo and Humalog before breakfast so I will try injecting a small amount first to see if I get a reaction before injection an entire dose.
