How you describe your discomfort at groin?
Is there any swelling in groin or at knee where discomfort is?
Any lumps at site of groin?
How about lumps in the area of groin?
Burning in groin ?
Can you tell names of antibiotics used?
I think it is side effect of sulfamethoxazole used.
Its temporary and will go away with passage of time.
This means oedema is there.
In this case you should go for a follow up check up.
Oedema means swelling.
Though I think healing is very good.
It will take time like 3 more weeks for your body to get rid of all.
Your body is still in recovery mode.
When complete healing of wound occur along with absence of any swelling.
Just keep moving your leg normally.Though not to stress too much this side.
But I suggest if you make a folllow up appointment if this does not go away in next 4 days-that will be great.
Wish you good health.
