I am having extreme pain on my left side slightly below and and to the right of my armpit. The pain does not bother me much when upright, or when working. (I am a carpet installer and do a lot of heavy lifting, etc.) The pain is worse at night if I try to roll over on my side in bed or on the sofa. Standing up is very painful, but once I m up it is not as bad. Sometimes, turning my head to the left, or back causes a lot of discomfort.I, m hoping it s a pinched nerve, or pulled muscle. The pain is very sharp, and almost immobilizing.
Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have sharp pain in armpit. Well there can be many reasons for symptoms you mention in query like cyst, breast cancer, angina, bacterial or viral infection, allergic reaction or lymph node swelling. I would suggest you to apply warm compresses on armpit, take over the counter antihistamine like Ben Chat Doctor.  Consult general practitioner for proper examination if the condition doesn't get improve. Doctor may order CT scan, mammogram, blood test and check tenderness and consistency. Doctor may prescribe antibiotics along with anti-inflammatory and immunosuppressants. Hope your concern has been resolved. Get Well Soon. Best Wishes,
