<s>[INST] Hi, I recently consumed MDMA crystals and by the way me and my friends felt can assume that it must have been cut with another chemical. I am fairly experienced with the usage of MDMA and infer this as the drug experience lasted in total about 14 hours, had terrible migraines and as bad an upset stomach. However after 1 or 2 days I started developing numb big toes but only  the tops of them. It has been a week or so and am wondering what to do and if I should be worried. This is the first time this is happening and where I stay, India, it is not so easy to talk to a doctor about such matters. Any help is appreciated.Top [/INST] Hi and welcome to HCM.This can definitely be effect of MDMA and this is the first thing to think of. Your body tells you that you must stop using it immidiately or ti may have very serious consequances. Various other symptoms can be caused by these drugs and this is just the beginnng of it. Numbness may indicate neural disorder but also itcan be blood clotting in your peripheral vessels. You need to see doctor if your symptoms persist.Wish you good health.Regards </s>
