So you think you have a skin bend. What do you do now?
You are sure, not sure or just do not know. As in medicine, where 10 are gathered together there will be at least eleven opinions. If you are talking about it you have at least admitted to yourself or persuaded your colleague that there is a problem. Do not blame the symptoms on the medicine you took last week or a bad bowl of mussels
If you are on a dive boat, you should have O2 available – use it if you are reasonably sure of the diagnosis and your distress justifies it. Then speak to a diving doctor, preferably one with a chamber attached so that if things go pear shaped, you will not be arriving unannounced
If you are close enough to the chamber and the symptoms are thought to warrant it, you may be recompressed. My experience is that this is effective only in the first hour or two. Otherwise you sit it out for a few hours or a few days. In the world of modern diving, your skin bend now needs proper evaluation by a diving physician.
