What Causes Chest Pain, Lumps In Throat, Cough And Brown Rashes On Leg?
Erythema nodosum - a panniculitis
Detailed Answer:
Hi, welcome to HCM,
Most likely Erythema nodosum a type of panniculitis.
It is the inflammation of the fat under the skin.Panniculitis feels thickened and woody to touch and demonstrate discolouration of the overlying skin, either reddening or darker, brownish pigmentation. the area is tender sometimes. After suppression of inflammation a slight depression in skin is noted.
As per your photo your inflammation phase of panniculitis is over and slight brownish yellow appearance is there.
panniculitis most commonly occurs due to trauma, cold or infection.
Freckles you are mentioning is actually insect bite most probably mosquito or bedbug as you have mentioned.
Blistering, peeling, or loosening of the skin is one of the side effect of propranolol but this localized effect is probably not due to this drug.
Swollen lymph node in neck needs proper investigation and treatment as throat infection and tuberculosis is one of the common cause of erythema nodosum, a type of panniculitis.
Diagnosis is by usually by clinical appearance and can be confirmed by excisional biopsy.
Hope this helps you.
Thanks.
