Hello medical hobbyists of mumsnet 
I am really reaching the end of my tether so all help appreciated.
I have moaned about this before but GP being useless.
I am almost 18 weeks pregnant and ill. Horribly, inexplicably ill. For about three weeks now I have been suffering pain in my right jaw- sometimes in my ear (it first presented itself as a swollen ear canal) sometimes in my teeth and sometimes in my jawbone. Latterly it has been in the side of my head on that side.
GP is clearly at a loss and has diagnosed variously:
-ear infection
-sinus infection
-TMJ
-virus
I've been prescribed erithromycene (allergic to penicillin), codydramol, codeine phosphate, feldene gel (to rub on jaw).
Alas none are really helping.
The pain is, I'm sure, intensifying. I haven't visited a dentist simply because it doesn't feel like tooth pain. I can't sleep, eating is hard, I can't work, can't concentrate.
I have also been suffering from bad HG and been hospitalised.
I would really appreciate any ideas, experiences or advice. I feel like I need to go back to GP but I want some ideas of ways forward.
TIA.
