Thanks for your query.
You have got a large bump filled with pus over knee Jt.You have to get it incised & drained by a surgeon And take antibiotics along with proper dressing for couple of days.Since it is close to knee joint do not neglect it or wait for it to subside of its own,As there is high risk of spreading it to knee joint.Thers is nothing related to scabies .It may be simple bacterial infection of subcutaneous tissue(Abscess)
