Brief Answer:
Continue Celestamine, add an ice block, Acetaminophen for headache, see Dr

Detailed Answer:
Hi and thanks for the query,

This can be very disturbing. I think taking Celestamine was a very good option. It might be necessary to increase slightly the dose of Celestamine you took and maybe use ice blocks on the area affected. This might help in controlling the pain and inflammation.

If this persists, you might have to see a doctor tomorrow. If the situation persists or aggravates, stronger anti allergic drugs or at some injections might be required.

Simple analgesics like Acetaminophen could be helpful with the headaches.

Thanks and kind regards as I wish you the best of health.
Feel free to ask further
