Be been having soreness in my legs is this normal?

Are you walking?

I had some soreness but I was on a prescription anti-inflammatory pre-surgery so I did suffer effects of going off those cold turkey. If you have swelling in any specific area or redness or tenderness to touch, please contact your Dr. There could be a possibility of blood clots if you are just post surgery.

could also be low in potassium, call your doctor

Sounds like your potassium maybe low and your electrolytes could be low. Start drinking gatorade, plenty of water and eat bananas. You may still want to check with your doctor also. Good luck
