Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain
severe pain in buttock can be due to causes like Brusitis, Sciatica,
Tendinopathy,
Piriformis syndrome, Osteoarthiritis, Coccydynia etc..
I would suggest you to consult an Orthopedician and get evaluated and he can advise you x ray and MRI Scan to ule out the exact cause of the problem and treatment can be planned according to the confirmed cause..
The physician can advise you anti-inflammatory painkillers, muscle relaxants, warm compresses, topical analgesic intments and
physiotherapy..
Avoid long duration of sitting in one place,,
Avoid continuous standing for long hours.
Loose weight if you are
overweight and do moderate workout after consulting a Physiotherapist..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
