hi mr ravikant thank u for sharing ur problem on HCM heavy cold and low grade fever for 2 moths i ll say is a matter of concern need to investigate properly cold attacks and finger lesions together suggest allergic manifestations do a skin allergy test but in allergy only there ll not be fever...that compels me to think me in some different ways low grade fever with heavy cold may occur in sinus diseases ...do a x-ray of paranasal sinuses is there any cough associated???? if yes u should have to exclude a chest x-ray to exclude tuberculosis apply calamine lotion locally over the skin lesions so my prescription to you ll be - 1. x-ray PNS 2. chest x-ray 3. allergic skin test 4. serum total IgE assay 5. do have a consultation with ur dermatologist i think u ll get ur answer by following these steps thank u
