Hello and welcome
In my personal opinion you must get an appointment with your general surgeon
, the symptoms you are explaining are might be Varicose and you may need surgery to get cured.
It is not an emergency but you should consult your surgeon soon. Meanwhile wear elastic soaks specially made for varicose veins
till the height you have these type to veins. Take anti-inflammatory and analgesic
drugs if you feel pain on legs. The lumps may be related to these veins.
Best Wishes and have a good time.
