Hi there i have had the same problem for years the same knee everything the same as you Weird , Please take care ...........Bob
Hello and hope you are doing well.
The ‘bump’ could be an abscess, which is a collection of pus. Please don't venture to meddle as this could promote the infection. The abscess may need to be drained and you may need antibiotic coverage to tackle the infection. You may need to consult your primary care physician who will examine you and initiate appropriate therapy. In the meantime you can take OTC pain medication Ibuprofen. Ensure to take this medication after food to avoid gastritis.
Hope this helped and do keep us posted.
I have the same on my right knee it's completely solid and I've tried a lot of things such as popping, putting a needle to it and also dug my nail into it due to the ugliness. I don't wear dresses skirts or shorts because of it. If you find out how to get rid of it please let me know
