Hi Dear!!Thanks for your query to HCM.
Read your query and understood your health concern.I feel concerned about your health issues.
Based on the facts of your query, You seem to suffer from-
Right Ring Finger-with Reynaud's Syndrome- with precipitate blue/ black cyanosis
with ICING done by you.Tingling
/ pins / needles is from revascularisation -a sign of recovery.
Other Causes of such episodes needs to be ruled out like Throbo-angitis obliterance(TAO)with cholesterol
emobilisation with obesity.Smoking
and Tobacco chewing
also could be accompanying reasons.
Consult Physician / and get the Color Dopler study to rule out the peripheral arterial diseases and treat it with vasodilators /and needful drugs.
Hope this reply would help you to plan further treatment with your doctors there.
Welcome for further query in this regard if any.
