The first thing that would come to my mind regarding your symptoms would be your drug
usage, secondly I think you mentioned how you would stay up for 2 days ? This is certainlely not very healthy either, even though I know it's pretty comon for Meth
-Users to stay up for 2-3 days without feeling like any kind of muscle pain.
The pain and the inflammation that you describe could also be triggered by something else than drugs
, A throbbing pain in the leg is an indication that there is some problem in its structural components: bones, muscles, tendons, and nerves. It's too early too talk about a Thrombophlebitis yet, but I would strongly suggest that you seek medical attention if it happen again.
