<s>[INST] Hi, I've had a dull pain in my left side for the past 4yrs when I lie on my back. I have to sleep on either side, because the pain can be unbearable when on my back.  I had a very bad cold that lasted about 4weeks about 4 years ago. and feel that maybe this is what caused my problem.  May there was an infection at the time, and I should have looked in to medical attention and possible antibiotics.  I am not a smoker.  I do not take drugs... just Tylenol to ease daily pains.  I am a 47 year old female in good health.  Please help! [/INST] Hello,Thanks for posting to HCM,Taking too much of Tylenol may cause sever liver disease.For cold take tab. wikoryl twice a day.For back pain take cap.secode oil. once at night in a day.Regards. </s>
