I get a “swimming” sensation in my head particularly at night when I’m falling off to sleep. I abruptly wake up as it feels like I’m falling for a split second. Currently, I’m having neuropathy down my right arm to my first two fingers finger tips which are numb. The pain goes down the tricep across the back elbow and down the forearm. I am told I have hashimotos thyroid issues as well. Would either of these cause the “swimming” and “falling” sensations? Any ideas?
