Hello Welcome to HCM. Sorry to hear that from you.
Basically you are suffering from renal or ureteric or bladder calculus.
Need few details as
1. Is scan done? Usg or CT scan
2. Your age
Anyway, the complaints that you are telling are true. It happens due to ureteric calculus because various nerves are involved in that process.
Depending on the location of stone, you experience pain all the way to thighs and sometimes leg as you mentioned.
So do not panic or worry.
Please take medications when you have pain. Take tablet
ultracet.
And you should recover well. Drink lot of water.
If pain continues, go for CT or USG scan to know the status of remaining calculus if any.
I'm there to clarify all your doubts, feel free to contact me.
