[|Human|] i took some molly and my heart started beating fast and felt like it was beating irregular or skipping beats. this lasted for about 2-3 hours. i was terrified now my left arm feels heavy/ numb. I also did about 1/2 - 1 gram of cocaine less than 24 hours before i took the molly. I was finally able to slow my heart rate and get some sleep, i slept for about 7 hours straight. Now however my left arm is still is sore/ heavy. What happened to me?
[|AI|]  Hello! Welcome on Chat Doctor! I carefully passed through your question and would explain that your symptoms (heaviness in the arm) could be related to a stroke. You should know that it is quite normal to have an irregular heart beat after taking molly or cocaine. But, from the other hand the irregular heart beat can cause cardio embolism to the brain, leading to a stroke. Cocaine itself can also cause spasms of the brain arteries, leading to an increased risk for stroke.  For this reason, I would recommend going to the ER for a careful physical exam and some tests: - a brain CT scan- a resting ECG- a chest X-ray study-some blood lab tests (complete blood count, kidney and liver function tests, fasting glucose, blood electrolytes). Hope you will find this answer helpful! Wishing good health,
