Welcome to health care magic.
1.The most possible cause in this case is ganglions in the joint from the joint spaces. Next possible cause could be infective aetiology with collection of pus within. If you are male - the other possible cause could be hair
follicle infection.
2.The remedy in this case - do not squeeze, compress, scratch the lumps as you will be complicating in that way,and delay healing process.
3.Treatment in this case includes a course of antibiotics, maintain local hygiene.
4.If lumps are big and not responding to treatment - an
incision and drainage followed by a course of antibiotics.
5.In case of ganglions, generally monitored - if symptomatic needs excision and drainage. Good luck.
Hope i have answered your query,
any thing to ask do not hesitate to ask.
