Welcome to Healthcare Magic Forum
A person visits a doctor, not just to take medication, to find the cause of his illnesss, the name (diagnosis ) of his disease, and to know what other measures (diet and lifestlye changes) are required. Visit a physician or better an orthopedician to find out why do you have pain, and espcially if pain killers are not working.
It will not create a problem, painkillers do not harm in 3-5 days, but should not be taken for long time.
Secondly, if there is nerve
compression, muscular spasm, bad posture, incorrect chair/sleeping mattress...medicine will not help.
is required, as well.
Meanwhile takerest, avoid sitting infront of laptop/pc/tv, hot water compress/bottle will help .
