Hello dear. Welcome to Healthcaremagic. I read your query and I understand your concern. I think you should consider visiting your family doctor because he will do a physical examination and will see if you need any examination done . It can t be said what they are without seeing. Take care. Hope my answer was helpful, if you have any other questions I ll be glad to help you. Best regards. Dr.Olgeta Xhufka ( general and family physician ).
