Hello and welcome to HCM.
The pain you described may be due to
blood clots getting formed in those dilated
spider veins or also called
varicose veins.
If I were your treating doctor,I recommend,
-Advice investigations like Colour Doppler for blood circulation of legs,blood coagulation factors tests,USG abdo. for detecting underlying cause.
- Apply compression stocking to the leg.
-Maintain the skin hygiene and moisture over the veins.
-Sit or sleep with the leg elevated.
-Avoid standing for too long at one place.Do frequent ankle exercises like doing flexion,extension,rotational movements at ankles joint.
-Avoid smoking.
-If the symptoms persist or ulceration develops at site,visit to surgeon for consideration of options like
sclerotherapy or ligation operation.
-Keep a watch over symptoms like sudden
shortness of breath,cough,chest pain,headache,vision problem,weakness of limbs eye and report immediately to ER if anything of such happens.
