I had experienced the rash-like bumps on
my inner thighs, calves and arms. This was sometimes very mild, but got very bad and extremely painful in February. At first, no one could diagnose it: not my Naturopath nor two dermatologists.
I did do a biopsy, which was sent for a second opinion, to finally get the diagnosis.
What has helped me the most is being on a gluten free diet, per my ND. Gluten can cause a lot of inflammation in the body, including the skin.
