Hello XXXXXXX
thanks for the query
Keflex contains the active ingredient cephalexin which belongs to a class of antibiotics called cephalosporins. Cephalosporins are known to cause hypersensitivity reactions including skin and mucous membranes ( lips, mouth, urethra) reactions.
It is very possible that what you have described is a reaction to the drug and it could be very severe if you continue the drug.
So, the first thing to do is to stop all the drugs you are taking at least for today and then XXXXXXX your doctor tomorrow for a review of all your drugs and possible change of the antibiotic. Meanwhile you should gurgle warm salty water regularly. Other common antibiotics known to cause such an adverse effects include; penicillins and bactrim (cotrimoxazole)
Hope this answers your query. If you have further query, i will be glad to help.
Best regards.

Thank you for your response.
I did contact my family physician Monday morning (did not take 2nd dosage of keflex on Sunday), and she is on vacation this week. The nurse practioner agreed that I may have started having a reaction to the antibiotic, and advised me to discontinue. Seeing I had been on it for the 4 out of 5 days, she suggested not prescribing a different antibiotic at this time. Unless symptoms.s reoccur, I follow up with a urinalysis and blood work next week.
I had a question regarding "spots" on the lung. I was informed that they also found a 2 cm "spot" on the lower left lobe. I know some refer to "having spots", but I didn't think "spot" was a medical term. My understanding is anything 2 cm or less is a nodule, anything greater is considered a mass. Am I correct? My physician vaguely addressed it to me, and said not to worry about it.
What steps should I take to ensure that it is in fact, nothing? My father, both of my
grandparents, and 2 aunts to lung cancer. My father and grandfather were the only smokers. Cancer has been prevalent on both sides of my family, which makes it difficult for me to ignore.
I would greatly appreciate any advisement you may be able to provide to me.
Thank you. XXXXXXX XXXXXXX

Hello XXXXXXX
thanks once more for the query,
It would appear you have what is known as solitary pulmonary nodule (SPN) which is a single abnormality in the lungs which is less than 3cm.
An SPN is rarely associated with other abnormality as most cases are benign and individuals with SPN do not experience symptoms. SPNs are usually noticed by chance on either X-rays or CT scans taken for another reason.
Though most SPNs are benign (noncancerous), they may represent an early stage of primary lung cancer or may indicate a secondary or metastatic cancer from another part of the body to the affected lung. Thus determining whether the SPN seen on the chest X-ray or chest CT scan is benign or malignant (cancerous) is important as early diagnosis could lead to urgent and effective management which is needed in cancer management.
You will need to XXXXXXX pneumologist( specialist in Lung medicine) to rule out possible malignant causes. Passive smoking of cigarette (being beside someone who smokes) is also a risk factor for smoking.
