<s>[INST] Hi over the last few days i have been experiencing periods of uncontrollable shivering, a feeling of weakness and sensitivity and a tightness in my chest. I have a mucus cough at the moment. It is worth mentioning that am awaiting results from a sexual health check as i fear i may have put myself at risk to an STD over the summer. Any idea what is wrong with me and if it is all linked?? [/INST] Brief Ans-Dull pain under right ribs.../ Under Evaluation Dear!! Thanks for your query to Chat Doctor.
