Im 51, 55, and weigh 236 lbs.; I take levothyroxine for thyroid problems. My total  cholesterol is 261, and LDL is at 195 as of last week. I seem to have caught a bad cold. My question is, is it normal to have bad pain mostly in left side of chest and radiates into middle of shoulder blades and also all the way down the left arm just when I cough real hard? It goes away quickly and doesnt happen every time I cough, but hurts when it does. My cough is deep into chest and is only productive first thing in the morning. At this time, it produces brownish looking phlegm.
Pain during the strong cough indicates may be due to muscles or nerves irritation, brown phlegm is due to strong cough no need to worry it is normal, cough persists for longtime then you should be concerned. Your cholesterol levels are high this can occur due to low thyroxine dosage than required for your body, once check with your endocrinologist and adjust the dose.
