As they say, I “chilled” my forehead. I experienced a “shooting” pain in the area between the eyebrows, the upper jaw. The neuralgia of the first branch of the trigeminal nerve was determined (it was bilateral, although one of the neurologists categorically asserted that bilateral trigeminal neuralgia never happens). I was prescribed Gabapentin and analgesics. It helped. But sometimes it appears again at the first serious hypothermia and I took Gabapentin and analgesics. It helped again. Droughts and cold are frequent phenomena, so I understand that I need to “wrap up in layers”.
I was prescribed Gabapentin for treating a long-lasting pains in the shoulder joint. I’m taking gabapentin 2 capsules for 2 weeks at night, as it is at night that I experience a strong pain in my shoulder after a serious injury. First, I took 1 capsule (300 mg). But I did not help, switched to 2 – it helped, there are no special consequences. I like taking Gabapentin so that there are no consequences from it, and as you know, in the case of potent painkillers, the consequences are bad, as it is difficult to live a normal life during the day. So why I choose Gabapentin!
