Bangkjok to Pattaya is 150 km- About 2 hr 30 minutes
Here is a review of Shankar's 2.0
You should be more specific in your question. Which country are you from ? or are you looking for online sources ?
I amy be able to help if you are more specific.
Usually this occurs while lying down or being seated. Quickly standup and .. it will be gone within a second. You may hesitate to standup... but just do it.. and the pain will be gone immediately.
Try it and thank me !!!!
