hello! I am a 19 year old female ! I have been experiencing random swelling spots in on my body! there is not pain associated no redness ! if I hadn't seen it I would've never known. last week I had a fairly large swollen area on the upper right side of my back. it stayed swollen for about 24 hours and then disappeared. now I have the same swollen spot on my lower left side right under my Breast. it just feels like fat.not hard or painful. this spot how ever was applied hard pressure during the day . I am a nursing student and my peers were trying to palpate the heart. I really hope someone may be able to tell me what's wrong. this isn't a normal reaction for me ! thanks !
