Hello,
Welcome, and thanks for sharing your concern
I went through your query, and I feel, you need to answer some of my questions,
1 How long since have you been playing
2 Have you consulted in the past for this and if yes what was the diagnosis than
3 do your veins swell on long standing also.
your history suggest you are suffering from,
varicose veins, and this will need surgery if it is beyond one limit, otherwise in early cases, pressure stockings can help.
Also check for your blood pressure and sugar level.
I hope my advice would have been useful, in decision making regarding your treatment, still if you have any clarifications or doubts feel free to contact back.
Thanks.
