Erythema nodosum is most common on the shins, but it may also occur on other areas of the body (buttocks, calves, ankles, thighs, and arms).
The lesions begin as flat, firm, hot, red, painful lumps approximately an inch across. Within a few days they may become purplish, then over several weeks fade to a brownish, flat patch.
Other symptoms may include:
Fever General ill feeling (malaise) Joint aches Skin redness, inflammation, or irritation Swelling of the leg or other affected area
The red and inflamed skin symptoms may regress to a bruise-like appearance.
