I am a 40 year old female. Symptoms started with severe knee pain and inability to walk 15 months ago. Orthopedic surgeons could only find small meniscal tears. 2 surgeries last year without relief. Had cultures done which were presumptively positive but final cultures negative. 6 weeks antibiotic prophylaxis. Have been unable to walk and missed lots of work past year. The last six weeks present with severe leg and knee pain on the left. First thought DVT. Took blood thinners after positive Doppler. Then had NOT left leg with mass suspicious for abscess. Cultures negative after aspiration. Experiencing severe pain and burning in feet unilaterally. Still unable to walk six weeks now without use of a cane. Having some night sweats and low grade fevers in evening time. Suggested that labs for Lymes, lupus, rheumatoid arthritis, and mycoplasma be done. Mycoplasma IgG high at 215. IgM negative. CRP 4. ESR 68. Any suggestions? Running out of options and answers.
