Dear member, Thanks for writing to healthcare magic. enlargement of the axillary tail of the breast may cause a soft lump in the armpit. pain in the calf above ankle May be due to unnoticed blunt trauma. I would recommend you to take a safe painkiller like dolo 650 mg thrice a day for 2 days along with hot pack at the site. Take your prescription medications of iron and calcium regularly. I don t think your symptoms are related to carpet tunnel syndrome. Kindly mention the armpit lump to Your doctor in next visit. If required an ultrasound may be done as per the discretion of the doctor. Thanks. Dr Bhagyashree.
