Please be careful taking ibuprofen. It isn’t advised for the over 65’s and, if taken needs something to protect your tummy eg omeprazole. I’ve never found doctors to be very good with problems like this although it might be an idea to have an x ray. If it’s soft tissue damage that won’t show up anyway. I’ve found chiropractors and physios to be more helpful and knowledgeable. I wouldn’t advise pushing yourself. It will need rest, elevation, heat or cold or both. I take turmeric for my joints but it can’t be taken with some medication. I do use ibuprofen gel if I have a flare up: it did work better than my long time favourite Voltarol recently. And I now do the pre knee replacement knee exercises to strengthen the muscles round my knee. I also use a patella strap sometimes although I sometimes think it make my knee even more sore.
