Welcome to HCM
We understand your concerns
I went through your description. I suggest you not to worry much. The tingling sensation
could be due to diabetes
or varicose veins
. But in those cases, the sensation should have been present almost every time.
Another possibility is "could be nothing". Just a sensation. Try massaging the area with sesame oil twice a day and most of the cases should be relieved of the symptoms. If no relief found, consult a physician for further advice. You might need it.
Hope this answers your query. Available for further clarifications.
