For most cases of MS-related headaches, the treatment is the same as it would be in people without MS. However, it is important to see your neurologist or the physician that is treating your MS, as certain drugs may work better to treat your headaches, depending on the cause.
It is also possible that some of the medications that you are currently taking for your MS or MS symptoms could be causing the headaches, in which case the doctor may want to alter how you take them, change to another drug or have ideas on how to cope with this side effect. But as you said no doctor could help you out, i'd say consult good neurologists or MS professional online! They're a good a source of help too. If you don't have the access to a good doctor or physician then i guess, consulting them online helps too.
Good Luck dear!
