PLEASE help me...I cant walk

I did my Test E/Tren A shot last Friday from the same bottles I've been using now for weeks...My kids were here and I don't think I cleaned the stoppers or my skin real well with alcohol BC I was in a hurry. It was sore Sat and Sun but by Monday I could barely walk...it is not hot, neither am I(no temp), no red streaks, no red marks or any redness...just swollen and EXTREMELY painful. I went to Urgent Care Tues and told the Dr. the truth and she put me on Keflex and Bactrim but its now Sat and I am still in immense pain...My friend says BC I have a lot of scar tissue(been using for almost 20yrs) the crystals probably fell out of the oil and it will go away...still no fever and the area looks the same its just hard to walk and I definitely can't train...please help me

PLEASE help me...I cant walk
