Hi,Dear thanks for the query to HCM virtual clinic.
I studied your query in full details updated from you.I understood your health concerns.
Based on your query data, In my opinion You seem to have
Ganglion lump which snaps when stretching your ankle.Itch/tingly/strange feeling is due to Ganglion
Cyst only.
X-ry of anke and CT study would confirm its origin from
Synovial joint / or tendon sheaths.
Treatment-
Endoscopic
Laser Ablation of Synovial Histiocytoma-a hamaromatous swelling would resolve this issue forever.
No medications would help it,as its chronic.
Other causes-could be
bursitis on anterior ankle/ or synovial granuluma, which needs to be ruled out in your case.
Hope this would resolve your query and worry.
Welcome for any further query in this regard to ME.I would love to help you out
Awaiting for any further query.
Wish you fast recovery from this intriguing health problem.
Have a Good Day.
