Upon first getting sick I had a lot of nausea and vomiting but this subsided after roughly 3 months. I now however get terrible stomach cramping and pain moving from left to right whenever I take any painkillers. I have given up entirely on aspirin and ibuprofen (NSAIDs) as these cause me too much distress and pain so I now manage my headaches with 1-2 paracetamol whenever I have to however even 1000mg of paracetamol cause me some cramping/pain. Is this something anyone else experiences? Strangely my stomach isn't too bad whenever I don't take the drugs but one of my main symptom for ME is headaches and migraines so sometimes I don't have the choice.
