It is an inflammatory disorder that affects subcutaneous fat and also the type of panniculitis.

The acute erythema nodosum symptoms are tender bumps, and we can locate them in the shins. They get puffed up on and off for weeks; later, they diminish and vanish with the mark. After some time, other lumps may arise elsewhere. Because there is no basis that lesions will appear at the same place. This process takes place for some weeks to months, and without realizing it will gradually dissipate.

It is not the case in chronic erythema nodosum, as it may take a year to heal. With scattered recurrences in various patterns, it can occur even if the underlying disease exists or not.
