Hello and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
The information you have given is incomplete like the age, gender, and purpose of taking
Gabapentin. Common side effects of gabapentin include sleepiness,
dizziness, fatigue, clumsiness while walking, visual changes, including
double vision, tremor, running nose, weight gain, and
indigestion. Stiff joints and night time cold sweats could be due to inflammation of the joints. You need to consult your treating doctor for further evaluation to rule out
rheumatoid arthritis and other inflammatory joint conditions.
Hope this answers your query. Let me know if I can assist you further.
Regards,
Dr. Mohammed Taher Ali
