Hi everyone, thank you so much for your comments, suggestions and support. It is such a relief to have your input. I'm not sure how to comment per reponse (newbie) but hope this is picked up.

To your comments:
I'm afraid I can't remember which specific antibiotics I had but the ones named above don't look familiar. Could effects from antibiotics come on several weeks after completing the course? I will talk to GP about this possibility thank you.

My baby was 11 weeks old when this began and is now four months. I am no longer nursing so can take ibuprofen which takes the edge off the pain but not the tingling and burning sensations. I will start some new mum supplements as suggested, thank you.

Thank you also for the MS information

Re lymes, I haven't had any rashes or illness other than described nor any bites that I've noticed. I haven't been camping or anywhere likely to pick up a tick bite. Do you still think this is possible? If so I'll also raise this with the GP. Thank you for the suggestion

My baby still has night feeds so fatigue is definitely in my life although hubby is a great help. I definitely feel worse with the pains and tingling when particularly tired.

Is anyone able to suggest what rheumatic conditions may present like this and so suddenly? I am keen to go to GP armed with as much info as possible as they seem keen on suggesting this is driven by anxiety... Which I am very sure it isn't.

Thank you again so much for your time.
