I am bipolar. I had urticaria last month and then the doctor prescribed me some medication. It healed totally but afterwards, it just started again yesterday.

 I went to another dermatologist today (because I moved to a new city). He prescribed me medication and asked me whether I had sleeping issues. Then he said my urticaria might be psychological or maybe because of the hot weather.

 Nowadays, it is correct that I sleep less than usual (6-7 hours whereas 8-9 is my usual), have more energy, and read a lot. I was already suspecting before visiting the dermatologist about having hypomania.

Is there anyone having similar issues or knowledge on this? i.e bipolar/hypomania triggering skin conditions like urticaria.

Note: I will talk to my psychiatrist as soon as possible, just asking for your experience or any comments.
