[|Human|] I am feeling twinges in my legs mostly calves. Last night I had an incident that woke me up and I felt as if I would die. Pulse had an irregular beat every 7 beats or so. Am taking cephalexin for allergy, related issue causing breathing problems. Is this type of stuff side effects? Took cephalexin for dental issues without incident.
[|AI|]  Hello, I have studied your case. You might be having the side effect of medicine, or it can be due to anxiety attack also. I would suggest you take following steps.1. Stop cephalexin immediately.2. Discuss with your dentist if you need to continue antibiotics.3. Take collar tablet for anxiety. If symptoms continue then you need to discuss with a psychiatrist. I hope this answer will be useful for you. Let me know if there is any other followup questions. Thanks
