What Causes Pain And Tightness In Chest After Tooth Extraction?

Question: In may 2014 i had a wisdom teeth extraction after having a blocked jaw cause of it, i don't know if that had anything to do with it but afterwards i started having a severe laryngitis with mild fever and swollen lymph nodes during which i had an episode of swollen wrists, arms and feet. After several visits to the doctor, ecographies and blood tests, i was diagnosed in july with mononucleosis caused by EBV, having a high level of EBV antibodies. The laryngitis went away but i was still having an awful sore throat, with a sharp pain, went to several ENT doctors but they said but neck looked alright. In september my salivary glands got swollen and i was still having that sore throat, after a visit to an infectious disease specialist, i was diagnosed with mumps based on blood tests because i previously had mumps during childhood as well. The throat ache was still there but took several types of antibiotics prescribed by dotors and it wasn't that severe anymore. Meanwhile i started having pain in my chest area, tightness, and i was breathing with difficulty, felt likw choking at times, i was sent to take an xray and had a month later a breathing test which didn't have a very good result, repeated it after a week of bronchitis medicines and it was ok. I also started having wrists pain at times and numbess of hands and lega and a tingling which was at first in the hands and lega area but at times it spread around all over the body, i still have those symptoms at present and that concerns me a lot. I am currently on a treatment with penicilin injections cause my ASO titer is a little high, it got eveb higher after i repeated the blood test for that, 4 weeks after starting the injection treatment. Is it normal to have wrist pain and numbness and tinglings if the ASO titer is 247? Should i take some other tests for that? If so, which ones? I forgot to mention i am 27 years old.
Thank you in advance!
