So I consider myself a relatively healthy 22 year old but recently around November I've started feeling this incredibly annoying pins and needles which turns into itching feeling across my spine, which usually goes into my arms, hands and feet. At first, I thought this was from smoking nicotine so I quit that however the symptoms persisted. It was incredibly bad when I went to workout and I drank a bang energy drink (which I normally do) and my whole body was just consumed by the pins and needles feeling and I wasn't able to properly function for an hour. Since then, I haven't been able to exercise. I noticed that I feel like this whenever I get too hot, nervous, anxious or when I'm about to sweat. A remedy that I've been able to find was smoking marijuana, which inhibits those feelings for a while. It's also incredibly bad whenever I engage in sexual intercourse, (I know this might be too much information) but when I'm about to ejaculate my entire legs, lower back, buttocks and feet are just overwhelmed with the itchy feeling. I recently went to the doctor and I did the usual check-up blood tests and nothing seemed abnormal. After scooping around on the internet I do believe that I suffer from an overactive sympathic nervous system. I've just recently changed my insurance to a PPO so that I'd be able to go to a neurologist. Has anyone else felt like this? Is there anyway to feel normal again? I just want to live the life I had prior and the symptoms really lower my quality of life.
