Henoch-Schonlein?: Do you think you might have chilblains or cryoglobulinemia instead? Henoch-Schonlein is a serious business when you're an adult. If you were given this diagnosis and it's not classic, consider a second opinion. If it IS HSP, I'll bet it's a coincidence but there's many unknowns. Best wishes.

Unrelated: HSP, if you truly have it did not arise from a bug bite or becoming cold. It is an odd fluke of the immune system, sometimes triggered by group A strep or other infections. It triggers antibody production where some of the antibodies attack your tissues by mistake. It can be very painful & often mimics other diseases. It can cause significant kidney injury. You should follow up with your doc.
