Hello, this is Kitt. I am sorry but we really cannot answer your question. I feel you should make an appointment to see your doctor as we are not healthcare professionals and can not dx. Our forum is a support forum and we can support you and help you through the anxiety.
Try not to over think the calf problem but get it evaluated by a physician and know that if it is a phelbitis or something else your physician will plan your care.
Take some deep breathes and know you will be ok.
Take care and good luck. Keep posting for support with your anxiety.
