i have had pain in my left knee for 8 days now, cannot bend the knee it feels very tight, and there is a lump to the left of the knee cap, i am able to walk and stand but this is very uncomfortable. ive been taking Ibuprofen 2 x 200mg 4 x daily for 8 days and went to A & E 4 days ago but they were not very helpful, just told me to rest the leg, i did not even get to see a doctor just a nurse!! should i make an appointment to see my GP? Thanks :-)
