On my right arm on inside of elbow close to bycep I have a small lump not really round kinda long and just noticed it been tired lately figured it was due to my 3 year old he has weird sleeping habits lately, been itchy today around stomach and back area was gonna take Benadryl but didn't have any, my glands aren't swollen anywhere. The only thing I have is renal glycoseria had it since I was little no problems with it really , I keep away from pop . I'm 41 and have 5 kids....did have a lump in area where gall bladder is they didn't figure out what it was, they did say I had gull stones, can still feel it size of a small bouncy ball just guessing
