Don't worry removal of the long saphenous vein is simply the common operation and as said I suspect you will only be grounded for the period arising from the general anaesthetic and until you are mobile
Mind you the modern operation uses a laser via a one cm incision under local anaesthetic and more normal people go back to work the next day. This is often the province of radiologists whilst surgeons do the stripping operation so you may want to ask your general practitioner to confirm the laser operation is not feasible for you
